To be honest I quite like him and feel like he has been misprofiled.
He's big framed and kind of fast so he can ride a challenge and carry the ball when needed but he's not really this destroyer that he was pitched as. He makes a lot of smart runs and likes to get in the box/in advanced positions and tries to progress the ball between the lines.
If we persist with the four midfielders then I think he could step in at the double pivot- both Busi and FdJ advance alot. We wouldn't play exactly the same, but we never played exactly the same when Keita came in for Xavi or Iniesta. Or before that- Van Bommel.
If the right offer, and the right alternative came I wouldn't complain at selling, but for now, not a big problem in the squad. Bigger issue's are Busi, Ferran, Raphinha and perhaps Eric.
