Then Cherki won't improve then, and will end up at a lower level.
Its on the player to step up.
For every Grealishyou have KDB, Sterling, Mahrez.
Its on the player if they don't want to improve and perform at that level.
He is also a low risk signing, cost very little really.
This training flair OUT of a player is just rubbish, its happened with 1 player Grealish ....and thats down to the player as much as anyone...Sane, Mahrez, Sterling, Doku all still do lots or flair, along with much more production under Pep.
Pep had Messi, Iniesta, Villa all showing flair ever single game.
Zlatan is hard to manage and has fallen out with many.
