You gotta love the Brits call a match...
Half-time in a cagey encounter. It's been interesting, but remains scoreless. Spain are struggling to create chances and Portugal are defending obdurately.
45+1 min: Iniesta tries to pick out Torres with a pass, but not for the first time, the striker looks off the pace.
45 min: There'll be one minute of added time.
44 min: Coentrao turns provider again, hoisting up a cross from the left. Tiago gallops into the box and leaps into the air, flashing a header across the face of goal and wide.
41 min: With Ramos and Puyol jogging back into position after a sortie into the Spain penalty area, Coentrao plays a through-ball for Almeida to chase. Iker Casillas sprints off his line and out of his penalty area to hack the ball clear ando nly just beats the Portugal striker to the chase.
39 min: Portugal attack down the left flank. Simao sends in a marvellous cross to Almeida and Ronaldo who are queuing up at the far post, with only Carles Puyol to mark them. Almeida leaps highest, but his header is only glancing and the ball skims wide. He really should have scored.
38 min: Spain are playing into Portugal's hands here. The Portuguese are sitting back, happy to defend as Spain repeatedly try to play through them, rather than around them. The only other way is over them, which they haven't tried yet.
35 min: Ramos on the rampage again, up the right wing. He pulls the ball back to Iniesta on the edge of the penalty area, but he's robbed of possession before he can pull the trigger. Moments later, the ball is rolled back to Xabi Alonso a few yards outside the Portugal penalty area, but his shot his blocked by one of three defenders who throw themselves in front of him when he shapes to shoot.
34 min: I forgot to mention earlier, by the way, that Spain are wearing their usual colours tonight, while Portugal's players are kitted out in white shirts, green shorts and white socks.
33 min: In the Portugal right-back position, Iniesta dinks the ball towards Xavi, who tries to divert it into the path of a Torres run. It's blocked by a defender.
31 min: Spain try to play their way through the centre, as is their wont, with Pique passing to Xavi between the lines of midfield and defence, then Xavi helping it on its way for Torres to chase. He puts his boot through the ball a bit too hard, leaving Torres with too much to do.
28 min: Xavi has a shot from about 30 yards. Close, but no cigar.
27 min: Despite the distance, Ronaldo has a go. The ball takes a horrible wobble at the last moment, forcing Iker Casillas to punch clear uncertainly. Luckily for him, it doesn't break kindly for any of the lurking Portuguese.
27 min: Xabi Alonso is late with a challenge on Coentrao, left of centre about 45 yards from the Spain goal. Spain have all eleven players back to defend, as Cristiano ronaldo stands over it.
24 min: Free-kick for Spain about 45 yards from goal, right of centre. Xavi pings the ball into the middle of the penalty area, but it's half-cleared. Assorted Spain players ping the ball to each other around just outside the left hand side of the penalty, waiting for a space to open or a team-mate to dart into the box. Xavi eventually makes his move, but the through-ball is too meaty and rolls wide.
24 min: The camera cuts to Iker Casillas, who exhales in the traditional "Phew, that was close," style-e.
20 min: Portugal go close with the chance of the game after Ronaldo and Coentrao combined marvellously down the left. Ronaldo, who has swapped wings with Simao, took out two defenders and played the ball inside two the left-back, who back-heeled it to Tiago, who had a pop. Casilla palmed that effort up in the air and it looked to be dropping over his head and into the goal, but he managed to fist it clear under pressure from Almeida, who was charging in on top of him.
19 min: From about 40 yards from the Spain goal, out on the right flank, Ronaldo stands over the free-kick, before failing to trouble Iker Casillas despite hitting the target.
15 min: It's all Spain at the moment, tiki-taka-ing the ball around the midfield to little effect. Portugal earn some respite when Sergio Ramos fouls Fabio Coentrao wide on the left flank, moments after Cristiano Ronaldo had threatened to burst with indignation after not getting a free-kick for being kicked by Carles Puyol.
14 min: Sergio Ramos gets forward, sending an inswinger of a cross towards the far post of the Portugal goal. It's too high for Torres and the ball sails out of play.
12 min: Xabi takes a shortish corner to Fernando Torres, standing with his back to goal just inside the Portugal penalty area. He swivels and hits the ball first-time, nearly catching Eduardo and his defence napping. The ball loops over the bar.
9 min: Whether by accident or design, Pepe clips Sergio Ramos's heels as he tries to run the ball out of defence, but the referee waves play on, tacitly suggesting Ramos was diving. The Spain full-back is unimpressed at having his good name traduced in this manner.
8 min: Portugal win two corners in a row, but nothing comes from either of them, bar a free-kick for Spain after Cristiano Ronaldo is penalised for offside during an impromptu bout of head tennis in the Spain penalty area.
6 min: Another good save from Eduardo, who is forced to block at his near post when David Villa cuts inside from the left, with Ricardo Costa backing off him, before unleashing a low, diagonal drive.
5 min: Xavi pings the ball out wide to Torres on the right flank and the striker cuts inside, before going down after a coming-together (so to speak) between he and Fabio Coentrao. Spain's fans appeal for a penalty, but it was something and nothing.
4 min: Corner for Spain, which Xavi takes from the left. Eduardo charges off his line to pluck his inswinger from the air. Good goalkeeping. It's been a lively start.
4 min: David Villa tries his luck and he too is on target. Eduardo makes his second save of the game.
3 min: Portugal are playing a 4-3-2-1, with Raul Meireles , Pepe and Tiago making up the three, Ronaldo and Simao on the right and left respectively, just behind Hugo Almeida.
1 min: They're off, and within a minute Fernando Torres brings a smart save from Portugal goalkeeper Eduardo, with a swerving shot from outside the penalty area.
How they'll line up: For Spain, Xabi Alonso and Sergio Busdquets will form the shield in front of the back four, with Xaiv on the right wing, Andres Iniesta on the left, with David Villa playing in behind Fernando Torres, who claims he is fully fit tonight for the first time in this tournament.
The teams are out and the national anthems are being played: Many of the Portugal team will be a bit too young to remember the famous day in 1139 when their country won independence from Spain, but Bruno Alves has probably told them all about it. They'll be up for this.
Pyramid Inverter Jonathan Wilson writes from South Africa: "Actually I thought that Japan v Paraguay game was rubbish," he protests. "When I say goals are over-rated it doesn't necessarily follow that every 0-0 is exquisite. Paraguay had one idea: let Morel cross it; but that was one more than Japan. Because of that they deserved to win, and it wasn't as bad as Ukraine v Swizterland four years ago, but it was dire." I don't know - if it was a woman he was talking about, you'd think he was protesting a bit too much.
On BBC, Alan Shearer is going out on a limb: "I just think Spain will edge it," he says. It's been tipping down with rain all day at the Green Point Stadium in Cape Town, which should make for a nice greasy surface.
Craven plea: With tonight marking the end of the last 16, I want to hear what your favourite moments of the tournament have been to date, so I can recycle them and pass them off as my own when James Richardson asks me for my favourite moments of the tournament to date in World Cup Daily tonight. So far I've got France, England crashing out to Germany and that bird taking up the vantage point on the Algeria goal-net to watch their scoreless draw with England.
Team news we've culled from the wires: Portugal striker Hugo Almeida and winger Simao Sabrosa are back in the starting lineup for the second round match against Iberian neighbours Spain.
With coach Carlos Queiroz having chopped and changed the team three times in the group stage, forward Almeida made one start, scoring in Portugal's 7-0 rout of North Korea.
The tall striker's inclusion, ahead of poacher Liedson, means Cristiano Ronaldo, who played in the middle of the attack in the final group game against Brazil, can move back to one of the flanks.
The other wing will be occupied by Simao. He replaces Danny, who has been struggling with the thigh injury he picked up late in the 0-0 draw against Brazil.
Spain coach Vicente del Bosque sends out the same starting team as in the 2-1 win over Chile. Midfielder Xabi Alonso has recovered from the sprained ankle he picked up in that match to start against the Portuguese.
Spain: 1-Iker Casillas; 15-Sergio Ramos, 3-Gerard Pique, 5-Carles Puyol, 11-Joan Capdevila; 14-Xabi Alonso, 8-Xavi, 6-Andres Iniesta, 16-Sergio Busquets; 9-Fernando Torres, 7-David Villa.
Subs: Valdes, Albiol, Marchena, Fabregas, Mata, Arbeloa, Pedro, Llorente, Javi Martinez, Silva, Jesus Navas, Reina.
Portugal: 1-Eduardo; 2-Bruno Alves, 21-Ricardo Costa, 6-Ricardo Carvalho, 23-Fabio Coentrao, 16-Raul Meireles, 15-Pepe, 19-Tiago, 7-Cristiano Ronaldo, 11-Simao Sabrosa, 18-Hugo Almeida.
Subs: Beto, Ferreira, Rolando, Duda, Mendes, Liedson, Danny, Miguel, Veloso, Ruben Amorim, Deco, Fernandes.
Referee: Hector Baldassi (Argentina)
Good evening everybody, particularly those of you who may be a little dazed and confused after waking up from the narcoleptic episode that led to you collapsing face down on your keyboard during Japan 0-0 Paraguay earlier today, the kind of match that would put most right-thinking people to sleep, but send guardian.co.uk/sport tactics correspondent Jonathan Wilson to bed with a smile on his face and what looks like a canoe in his pocket.
