His influence on the team's passing is very evident here. Look at his average position when on the ball AND off it; specifically the amount of time he was around the penalty box/left touchline area.
He played a lot of balls forward and always tried to look for that more progressive pass. Carrick came on, played good and added that urgency but his natural instinct, game and his mobility means he is always sat in the centre circle. He doesn't press because he lacks the athleticism and he doesn't dribble/move forward with the ball because he's happy to sweep things up. Unfortunately for us, that also means he's rarely an outlet for those passing triangles further up the pitch and he rarely ever moves with the ball. He's so relient and comfortable just passing to feet that he's forgotten he can advance several yards of unobstructed space himself.
Schweinsteiger will sit deep if the game calls for him but his natural tendancy is to move the ball forward and create situations for attacking play. He and Carrick, will never last as a 2 man midfield but if Schweinsteiger is fit, he should start any day of the week.
