There wasn't much to shield from, James McArthur or Joe Ledley wont strike fear into many teams as a centre midfield pairing. But even if they were better players it was more the way Palace played that day rather than the individuals, but, like you said wel agree to disagree.
I think that's an unfair question as with all them names you have listed its like as if there was no other option in any of the games.
I just think there have been a few games where we could have used someone else but haven't, the league cup game sticks in my mind, and also at various times during the season its felt as though its against some unwritten law that Besic and McCarthy cant play together without Barry which I don't believe myself, it should have been tried more than it has been so far this season imo.
It might be an unfair question but it is the one that Martinez has had to deal with - don't you think it a touch unfair of you to complain without taking into account the circumstances?
McCarthy - Injured Wolfsberg 27th Nov out for a month, back for Stoke on Dec 26th but breaks down next game vs Newcastle 28th Dec, only returns 7th Feb. Misses premier league games 13, 14 , 15 ,16 ,17, 20, 21 ,22 , 23
Osman - Injured vs West Ham 22 Nov, takes a while to diagnose problem so plays in a couple of games but not seen since 2 min cameo vs Man City 6th Dec. Missing league games 16 onwards
Gibson - last match 14th Nov for Ireland, first appearance on bench Crystal Palace. Misses games 12-22
Basically since end November until this week if we didn't want to play Barry our choices in midfield been to partner Besic with Barkley or a youth team player like Ledson. Perhaps we should have, especially in a game such as West Brom or Hull, but it isn't quite as straight forward as made out.
As for the Capital one league cup game it was at the end of September and Barry was rested for that game - Gibson and Besic were partnered together, Barry didn't even make the bench.
