He should go. A technically excellent player, but one for whom we’ve never found a proper role for. He also has to take some of the blame though. Even when we put him next to Matic and Herrera as the attacking LCM, he was inconsistent. Realistically, his best period only happened out of spite to a manager he clearly despised no longer being in charge.
I’ve never really been able to build any player-fan relationship with him either, considering his admonishment for all things United for what has seemingly been every international break for the past 5 years and blatant come-and-get-me pleas to any decent club who would listen. There have also been times where he simply has not run back. No excuse for that.
In conclusion, he’s brought more toxicity than good in his 6 years here. Sell him and build the midfield around Bruno by replacing him with a pure DM. I’d fancy a Bruno-new DM-current form Fred midfield next season under a top, progressive manager like ten Hag.
