Sack him
Elton's been on the Special Brew again but draws the same conclusion as everyone else has since last season.
Barkley's beef is with Fat Head, no one else, and if he was to leave then Roscoe would want to stay. Not sure how true that is like.
Saying that, I'd still sack Koeman tomorrow if there was a chance Barkley would stay and sign a new deal.
