I actually like the way he brought Coleman through, the idea of making mistakes at right wing was better than right back, I understood his ideas behind such a move. I also understand why he didn't just throw Barkley into the deep end, he was showing small glimpses of his quality but also making mistakes, so I agree that he didn't give him a consistent run but again I also understand the method behind the madness.
Lets both be honest now, there is not many people who thought Dier or Mustafi would make it at this level, if you are one of the few then I understand your sense of frustration. I follow a lot of football around the world and raved on about the likes of Aguero, Hazard, Lloris and such, Dier and Mustafi weren't exactly setting the world alight like those mentioned were.
Also take into account the likes of Arteta, Fellaini, Pienaar, Lescott, Jags, Baines, Anichebe, Vaughan, all players in the same bracket as those Martinez has given a chance to, I think its safe to say that Martinez fell on the likes of Galloway and stones due to injuries. The run in the team they have both had is just as likely to happen under Martinez as it is moyes although under Martinez it happened a lot quicker as someone else mentioned above.
