The Grealish situation is slightly different as he had a release cause, but I still believe they overpaid for him regardless. We tend to be shrewd in the market, so hope we pursue options elsewhere.
Their "four captains" have supposedly taken a pay cut or are in the process of doing so. Pique's decision was announced first, so Barcelona could register their new signings prior to the season beginning.
He had WB options but decided to go after Hakimi, which had a knock on effect.
The fact CHO played at WB for the last few games only to be dropped when it matters most makes you wonder.
I think he'll relish playing alongside another CF (should Tuchel field them both) instead of playing alone. He regularly played with Poulsen at Leipzing IIRC.
