Not a coach but I'll weigh in on this one anyway. The spine of the team is the most critical component. Identify the spine and then build from a defensive standpoint with players who have composure under pressure in the back.
Players with composure initiate and execute possession oriented attacks. Outside backs must have the ability to attack with and without the ball at their feet and to hit targets at distance. All players from front to back must get behind the ball when not in possession. The entire team must be able to protect a lead, manage their shape and execute counter attacks with extreme precision and discipline while always understanding defending is critical to winning.
Players up top who understand how to use their support vs having the 'go it alone' mentality are critical to dynamic movement and one time finishing required in the final third so as to overwhelm defenders while combining with midfielders and outside backs. Midfielders must be workhorses from box to box who are exceptional technical but simple players with 360 degree vision and a determination that borders on obsessiveness.
Finally, the keeper must be a kick-ass cat with exceptional reflexes and great foot skills as the anchor in the spine of the team. Such a structure allows for strength through all thirds with a heavy emphasis on defending while achieving the ability to dominate offensively.
