I think for all the good Fernandinho has been this season. His last few games were not that great in my opinion he seemed sloppy on the ball at times getting caught on the ball in the Leicester game nearly costing us a goal and his passing was not that great. Maybe it was the so many games he has played so far. Hopefully we see the best in Fernandhino when he is back in the team. Also think Fernando has done well with Delph and we look solid in midfield. Yaya is the biggest question mark. Cant play in the 2 in a central midfield push him up behind Kun then we might see the best of him but then we loose 1 of Silva , Sterling or KDB to keep him in the side while all have offered more this year compared to Yaya in my view.
