Similar to Pirlo, looooollllll.
To sum up, no he's not. Pirlo sometimes gets the ball and chooses the safe pass 20 yards to someone free on the wing, most of the time he doesn't, he finds an attacking forward pass and gets the team moving up the pitch, he's as comfortable in space in his own half as 10 yards outside the opposition box being closed down and turning into space and finding the killer pass.
Carrick ONLY does the sideways passing, its the easiest job in football today, he can't do the rest. In that sense Carrick is like EVERY player in football because everyone can pass sideways under no pressure to someone in plenty of space.
Carrick is crap, and Pirlo is NOT useless defensively, the two players have nothing in common, and Carrick isn't reliable.
If you take up one of the 11 positions on the pitch with a guy who sits in an area that requires defensive work, can't defend and isn't good going forwards, you're wasting a spot on the team, nothing less.
