Both that + the tensions with the rest of the management, unless it's all based on that team manager...
I mean he definitely did feck up a lot in the last 12 months:
not sacking Rose complete messed up their season, cost them a lot of good will with the fans and god knows what it did to the dressing room
not selling or extending Zakaria and Ginter in the summer is a small financial catastrophe for the club
he had the club pay €7.5m for a coach, who seems all but ready for the axe halfway through the season
having his love live interfere with club business isn't exactly professional
It's not surprising to hear that the rest of the club's management might have been questioning him.
