Jose Mourinho may have spent over £300million at Manchester United, but he still has a soft spot for a player brought in by David Moyes.
Marouane Fellaini has been a divisive figure among Red Devils' fans since joining the club from Everton in 2013.
However, the Belgian can always rely on his current manager to back him up.
When he was booed for giving away a penalty in last season's 1-1 draw with Everton, Mourinho stood by him.
Last month, when the United boss was asked about Luke Shaw's form in his press conference, he batted the question away by insisting that the midfielder was the player he was "worried" about, not the left-back.
The 29-year-old is out of contract at the end of the season and despite continued talk of an extension, he is yet to sign a new deal.
In fact, the Independent have made a huge claim about the extent of Mourinho's worries.
Understandably, the Portuguese is frustrated that a player that he views as key to his plans, primarily because of his physical presence in the middle of the park, has not been tied down.
United can't afford to upset Jose
The newspaper suggests that Ed Woodward and co need to ask fast, as they risk alienating the Special One further at a time when he's already being heavily linked with the PSG job.
Several reports claim that the Qatar-backed Parisians have identified him as their first-choice replacement for Unai Emery. On top of that, he recently said on French TV that he thought of the capital city as "magic".
It will be a huge worry for the board if Mourinho and Fellaini's futures are indeed linked.
There are very few players he sees as "untouchable", but it's claimed that for him, Fellaini joins Romelu Lukaku in that category.
What started as a fairly innocuous rumour seems to be gathering pace, especially with Manchester City apparently running away with the Premier League title.
Former United midfielder Johnny Giles has suggested in the Irish Independent that he is "certain" Mourinho wants to leave the Theatre of Dreams "as soon as he can find a way to sign on the dotted line for PSG".
As far as we know, Giles doesn't have any particular insight into the situation, but it's still unsettling that there are so many signs of uncertainty.
