Someone like Delph partnering him? Seriously mate can you not see how poor a central mid pairing that is? Look at the best midfields in Europe, even the best midfields in England, that pairing doesn't stack up at all.
Oh so Yaya and Fernandinho does? Or Yaya and Fernando? Or Yaya and Delph?
Yaya has played in 26/30 games I believe and we've been fucking shit all season, excluding the first five games which makes the last 25 stats even worse.
I'm sure you weren't scared by the thought of a Kante & Drinkwater or Dier & anyone else at Spurs at the start of the season and they've worked out pretty well.
The fact is you don't know until you give it a try, too many people on here think they know everything without giving it a chance and yet seem happy to stick with something that is evidently not working anymore.
