But Arteta left two years before he joined? And players in the mould of Pienaar are very hard to find and, actually, are becoming rarer and rare in the Prem when you look at a lot of other teams...
Gibson has had tons of injuries and it has nothing to do with him being marginalised. When he's played he hasn't performed or been able to perform to a high enough level to get ahead of Barry, McCarthy or Besic in the pecking order.
Oviedo, again, has had horrible injuries and has in no way being marginalised. Fellaini was sold because he wanted to leave and we rinsed United for him and used that money to get a quality striker in.
Naismith, again, for all his work ethic, is only suitable in one position and that is where Barkley plays. I think I know who i'd rather have and again we got a great fee for Naismith.
Martinez has got over 50 goals out of Lukaku, he's got over 10 assists out of Del this season who had a torrid time under a different manager last year at Sevilla. Besic, again, has been injured loads this season but when he's played he's been excellent. Rarely has the lad been fully fit and being on the bench so again your argument is a nothing point.
McCarthy, likewise, is in the team to do a job that he often does brilliantly and that is break up opposition play. When he gets forward - which Martinez often instructs him to - he has provided two assists this season - two months of which he has missed.
Funes-Mori has played over 20 games for us in his first season in English football and is now considered genuine competition/a first team regular. He has also scored 3 goals and got a couple of assists.
Galloway, again, is 19 years old and has now made over 20 appearances in the Premier League. He's a full back who is going to be a centre back. Tell me what more RM could have got out of him at this stage?
