Jose Mourinho is an imposing character who usually gets his own way.
But the now-Roma boss has had to manage disappointment in the past when certain decisions have gone against him. Back in 2009, the 59-year-old was in charge of Inter Milan and star striker Zlatan Ibrahimovic wanted out after attracting the attention of then serial winners, Barcelona.
The situation is not too dissimilar to the one Erik ten Hag currently finds himself in at Manchester United, with Cristiano Ronaldo recently rocking the club by announcing he wants to leave this summer and play for a side competing in the Champions League.
