That's because there's almost no world class midfielders who do the role we want. Fernandinho does more attacking than most other teams attacking midfielders.There will have been more than a few games where he gets more touches in the opposite area than anyone on the other side.
Then he's also got to defend very large spaces, and be very good on the ball, an excellent passer - ideal a better passer than Fernandinho too to switch it out to the wings and start counter attacks.
If you look at other top teams in Europe, no one really has that in 1 player except Barcelona and we aint getting Busquets.
So I think we need to look at box to box midfielders who are smart, and have the ability with the ball, who then can be taught the tactical role defensively. Fernandinho was a box to box midfielder before he came here, Busquets was not a pivot before Pep got hold of him.
We're at least 1 midfielder short as it is. Fernandinho turns 34 next season and I would not be surprised if this world cup takes a huge amount out of him as well, having no break between seasons at his age coming off this season playing every single game? Much as I love him, I would be surprised if he's the same player next year. Age catches up eventually.
I'd be surprised if we didn't buy 2 midfielders, and when you think back to our transfer targets last season, wanting Mendy+Bertrand, Walker+Alves, Pep's clearly not against stacking up two players who'd want to start in one position. Plus both could play further forward, and Pep will probably starting being more creative with formations next season.
Then with Yaya, Mangala and possibly Kompany on the way out, we could see Fernandinho be used more as a CB or as a utility player.
