The Belgian recently admitted his poor performances for Manchester United this season could be explained by fatigue following the World Cup in Russian Federation.
Meanwhile, defender Eric Bailly can fight through a hard spell at Old Trafford and become "very important" for the Premier League club, according to Valencia boss Marcelino.
As Manchester United step up their pursuit of Toby Alderweireld, it is clear that Tottenham Hotspur should reopen contract negotiations.
Senior sources at the club strongly denied the story to Press Association Sport at the time and it is understood that the manager still retains the backing of the United hierachy.
The 19-year-old is the real deal and United fans are desperate to see what he can do.
Mourinho was asked what he needs to do to coax consistently good performances out of the World Cup victor, but he was not happy with the line of questioning.
Beating Liverpool on the back of those two big occasions for them would be an incredible reminder of the not so distant past.
The Red Devils defence have not had the best of performance this term after conceding 26 times after 16 Premier League games.
Manchester United have had issues with playing out from the back as well as ongoing problems with utilising full-backs for them to be a unsafe threat going forward. If Juve draw and United win in Valencia, that would mean Mourinho and his team snatching the first place and a much easier draw. Football is football and anything can happen.it is a football match, a Champions League match.
But what has been clearer in recent weeks and months is that his trust in club-record signing Paul Pogba is not where it should be.
"Pogba, [Romelu] Lukaku, Sanchez isn't fit".
