I know its probably wrong, but i can't help but think that Moyes is coaching the skill out of Mirallas.
His first game against Leyton Orient I went to, he was class. I know it was only a struggling league 1 team but this leads onto my next point.
When he played against Oldham (in a similar position to Leyton Orient) he would just get the ball and run to the wing and cross it in, against oldham? He's not that kind of player.
But I don't think this is abnormal of him as of late, he doesn't cut inside or much, the flicks of skills and technique shown against Leyton Orient and Liverpool aren't there anymore, he almost never cuts inside anymore at all.
I don't know whether this has something to do with his injury but it seems very odd for his style to change so suddenly.
I also dont think he's playing in the right position, i know he's right footed but didn't he get 20+ goals in one season for Olympiakos playing on the left wing? Play him there a bit more, or even MAYBE behind the striker but only maybe.
Baffled me.
