Totally agree.
Fernando may have improved, but he was starting from such a low point that it would be difficult for him to have gotten any worse.
He'll get nowhere near a Guardiola side imo, he's nowhere near the required standard technically.
I expect Fernandinho to stay, he's perfectly suited to a Pep side, mobile, quick, athletic, good technique, intelligent with the ball.
He does like to load up the squad with midfielders. He often prefers a midfielder at centre back or full back than a specialist in those positions, because midfielders are so often better on the ball. And he usually lines up with 3 centre midfielders instead of two anyway.
With Yaya going, Fernando likely to, and us already being short there, I think it's sensible to buy 3 CM this summer.
Ideally I'd like to see:
one who can play as a pivote (anchorman) and as a box to box player - Gundogan
one who can play as a box to box player and as a winger - Isco
one who could play as a pivote, box to box player, or number 10 - Kroos or Pogba.
