Aaron Lennon has made a massive impact in the Premiership over the last few months. He has incredible pace and ability to beat people, as well as producing consistent dangerous balls into the box. Out of the few you named there zidane10 Lennon has by far the best form and his confidence must be sky-high (unlike Shaun W-P).
It looks as though Sven will play with one up (Crouch) and look to flood his midfield with either Lennon/Beckham on the right with either Ashley Cole or Wayne Bridge providing the width on the left.
With the players he has brought Sven has given himself a massive range of options in the tactics he can deploy plus he has unknown quantities at the international level such as Walcott, Lennon and Downing. Remember Owen's impact in 1998??
