Mikel Arteta has had to deal with a number of difficult situations during his time as Arsenal manager.
Granit Xhaka looked as though his time at the Emirates Stadium had come to an end before Arteta intervened and convinced the Swiss midfielder to stay, a decision which is now paying off for the Gunners. The Spaniard also took the decision to strip Pierre-Emerick Aubameyang of his club captaincy following a series of disciplinary issues which led to the Gabonese striker being left out of matchday squads and then being sold to Barcelona in the January transfer window earlier this year.
Erik ten Hag is facing a similar situation at Manchester United now after Cristiano Ronaldo refused to come on as a substitute during the 2-0 win against Tottenham. Ronaldo was keen to leave Old Trafford during the summer transfer window but the club opted to keep hold of the five-time Ballon d'Or winner despite interest from Chelsea.
