The defenders in this league are a step up from what he's been faced with all his career. He cant outpace them and that seriously limits his attacking potential. Pienaar is in the same boat but his saving grace has always been his retention of the ball. McGeady is not doing that. He's done a job defensively over the past few weeks, and a good one at that. But maybe that takes the energy away from what he should be out there to do. Very few wingers can do both tasks - Mirallas isn't even arsed about stepping into his own half, for example.
I like these types of players though. He's a got a trick or two in the bag and he produces them when confident. I've always suspected he's best over on the other wing where he can step inside onto his right. But I think Martinez might see Mirallas as wasted on the other flank with Coleman making surging runs.
