I don't know but if he wants to play football I don't hold it against him. He came and helped save the club and now he might just not want to waste the last year or so of his career as a sub.
Without trippier we lack creativity in the right. We need a right winger. Murphy/Almiron infront of tino/krafth is not good enough.
Howe won't change the team for ages probably until Europe is out the window. I would bet right now an avy and username bet then when Tonali or willock start making sub appearances that Longstaff doesn't come off.
