There will be games or moments in a game against teams that will sit back and sacrifice almost all attacking play, basically defending for their life. Arda is very valuable in this scenario. You need to have players who provide options on the ball in the last 3rd or near the box or even in the box. The best AMs we have who can do that are Iniesta and Arda Turan.
Nice option to have when we need to force things and risk it all. If only we had an option like that against 10 men Inter or 10 men Chelsea at Camp Nou things could've been very different. I'd have taken off a CB and put in a player like Turan every time.
I agree. He didn't play classic LW at all. He plays all around that left side. He was 2nd striker, winger, midfielder. He could play Iniesta's role in this form and with fintess and confidence level going high I think. Problem is we have 2 more players who can play there. We'll have trouble playing Iniesta, Arda, Gomes, Denis and Rakitic on only two spots.
Also, the problem seems to be that a lot of these players prefer left midfield side, rather than right midfield side.
