He wasn't the wrong type of player at all. He's someone who plays out wide but likes to influence things. A bit like Pienaar really.
The reason why he people think he wasn't needed is because he's playing averagely. If he was out of position, but playing him in the middle would release a star, he'd be put in the middle.
People just need to be patient. Given that he's our 2nd highest scorer and probably up there on the assists count I don't think there's too much room for consternation at this point.
If he's still like this in a year, then fair enough you might say we messed up on this one, but it's far too early yet.
