Cristiano Ronaldo is considering his future at Manchester United while he waits to discover who the next permanent manager will be.
Ronaldo has a contract until 2023 - but could leave United this summer if he doesn't agree with the managerial appointment.
And the revelation will pile huge pressure on new chief executive officer Richard Arnold to get the decision right.
Ralf Rangnick took charge on an interim basis at the end of November and is expected to take up the role of 'Senior Football Advisor' at Old Trafford on a two year deal ahead of next season.
Arnold, who will replace outgoing executive vice chairman Ed Woodward when he stands down on February 1, will now lead the club's search for the next full time boss.
Mauricio Pochettino, Erik Ten Hag and Brendan Rodgers are all under consideration as Arnold looks to appoint someone capable of returning United to the top of English football once again.
But the decision will have a huge bearing on whether or not Ronaldo, 36, decides to fulfil his contract at Old Trafford.
And although Rangnick is not thought to be under consideration for the job full time, Ronaldo has let it be known that he wouldn't support the German's appointment.
Ronaldo rejoined United from Juventus in the summer on a deal making him the highest paid player in the Premier League and was expected to help them challenge for trophies.
But his homecoming has not been like the one he imagined, with United sacking Ole Gunnar Solskjaer before finding themselves a staggering 22 points behind league leaders Manchester City and out of the title race.
A source said: "He thought it would be better than this. He's a born winner and want to be winning more trophies, so who the next manager turns out to be will help him decide his next move."
Arnold faces a huge challenge as he prepares to replace Woodward, but co-owner Joel Glazer has backed him to make United great again.
Glazer said: "I would like to thank Ed for his tireless work on behalf of Manchester United during his nine years as Executive Vice-Chairman and 16 years with the club.
"We are now looking forward to Richard and his leadership team opening a new phase in the club's evolution, with ambitious plans for investment in Old Trafford, the strengthening of our engagement with fans, and continued drive towards our most important objective - winning on the pitch."
Arnold said: "I am honoured to have the chance to serve this great club and its fans. I am determined to return that honour in any way I can."
