Sure, if we need him in the centre, play him there. But we didn't improve in that area when we made the change & we weakened the rb position.
Barca might have thought that about Mascherano at cb. But it became a way of getting more quality into the team. If Fernandinho got his shit together on the ball, he's a whole world better than most fullbacks we could find, who are usually deeply flawed & very expensive, some are slow & skillful, some are fast & shit, some are skillful fast & stupid, some can attack but not defend, etc etc.
There is no guarantee that the fulbacks we sign, will turn out better than the ones we have already. We just hope they will.
Having players who can solve potential problems is a godsend & is what Pellegrini should have been doing with the squad, & the kids, for 3 years.
I don't mind either way, but I'm sure Fern can learn that role & probably be as good as anyone else, is my point.
I thought he really struggled to find positioning in addition to the passing. Swansea had almost none of the ball when he was playing RB so he did very little defending. But if you use Clichy's positioning as a proxy for where Fernandinho should have been, Fernandinho was often 10 yards or so deeper and wasn't using the touchline to protect himself the way a natural wide player does. This would be my primary concern with this idea ... if you're going to play a position on the pitch you need to play it with confidence and move appropriately because your teammates will expect it. Fernandinho being so deep was a sign of not being sure and wanting to make sure he didn't get caught up the pitch. Admirable in the sense of sacrificing for the team but a sign that he wasn't comfortable in the role. But if he's going to be in wide positions as a full back he's going to need to learn the correct body shape and common movements of a full back in order to maximize his midfielder skills. I didn't think he did a good job of using the touchline or using his body positioning to open up options or create space yesterday.
