Just to put things into perspective, we are not the only team that has this problem, and other teams are dealing with it in a similar way.
Manchester United's most important midfielder, a player in his prime and a vital part of Mourinho's scintillating brand of football is refusing to sign a new contract with his current one set to expire in the summer. The papers say that Mourinho will not sanction a January sale even if it means his star player will leave on a free. Having signed for United for 27.5 million in 2013 one can imagine what his value would be in today's market, if Mourinho sees more value in keeping this full international and guaranteed starter until the end of the year instead of cashing in in January then surely this makes Klopp's stance on Can understandable given his role in the squad. Personally I can't imagine Mourinho's United without Marouane Fellaini, what a loss he will be to them next season and their supporters must fear for their chances of even qualifying for the CL without him.
