Carrick never reached these stats seasons back where we certainly didn't play much possession football, Schneiderlin is no doubt better and stronger defensively and would add the needed balance to line-up more attacking players in front of him, without need of Rooney or Fellaini playing in midfield.. this is no judging by stats but by common sense, when people try to argument without stats than it's numbers which are demanded when you show the stats to support your argument then it means almost nothing.
And take in note this: Carrick in his soon 34 is nowhere near mobile to play in such tempo like Schneiderlin, it is due to him and some other player like Fellaini, Rooney, RVP, etc we play such rather slowish possession football, Van Gaal never played this IRC, the only reason is that we play with players what we have! We are going to be much more aggressive once we enter the market and buy the appropriate players, I believe we're going total Voetbal unless Van Gaal decides it is time to suddenly change his philosophy at the last stage of his career, to change something which worked wonders and which made him coach he's now. And of course it will take some time to adjust his team, 15 players gone 6 in and counting.. Carrick will be a good squad player next couple of seasons and mentor to whoever will be his successor, it would be very unwise to set up a play around him when he's reaching the end of his career, there is a new team forming and it needs new impulse, let alone his recent injury troubles. And everyone who watched late Carrick knows that he's good when he doesn't play 50 games a season, he's much better fresh, use him like Scholes to some extent..
