Jose Mourinho has admitted United and England captain Wayne Rooney could leave before the Chinese transfer window closes next Tuesday, The Sun reports.
United’s record goalscorer has a $1.63 million (£1million) per week offer on the table to play in China.
It would make him the highest-paid footballer on the planet.
And asked if Rooney will still be here at the end of next week Mourinho said: “You have to ask him.
“I cannot guarantee that I’m here next week, how can I guarantee that a player is here next season?
“What I can guarantee is that if one day Wayne leaves the club it is not because I want him to leave the club.
“I would never push a legend of this club to another destiny.
“You have to ask him if he sees himself staying in the club for the rest of his career or sees himself moving.
“It is not a question for me because I am happy to have him. You have to ask him, not me. I was very open with you in the answer.
“I don’t want him to leave.”
Rooney has started just one game in the last nine.
He has 18 months left on his current $406,000 (£250,000) per week deal, but United do not seem keen to take up their option to extend it for a year.
The striker, who has missed the last two games due to a combination of root canal surgery on a tooth and a muscle problem, rejoined his teammates in training on Wednesday.
But the United and England skipper could only take part in the warm-up and Mourinho opted to leave him at home when the Red Devils travelled to Saint Etienne for the second leg of their Europa League last 32 second leg game.
Mourinho added: “Yes, he was doing the warming up and the basic things after warming up, but then when the training session was higher in intensity, he was not training. No chance for tomorrow, he is not here, he stayed back training, and let’s see for the weekend.”
According to reports, United could even make a profit on the 31-year-old. The Red Devils paid a transfer fee of $44 million (£27million) when they signed him from Everton in 2004. English newspapers have reported Chinese clubs could be willing to pay United up to $49 million (£30 million) to recruit Rooney before his current deal expires.
The deal would see Rooney return to the top spot on the list of the highest-paid footballers on the planet, leap-frogging Carlos Tevez (Shanghai Shenhua) and Oscar (Shanghai SIPG), who both recently moved to China.
Tevez only last year became the highest paid player on the planet when he signed with Shanhai Shenua for $1 million (£615,000) per week deal.
Rooney is set to earn more than 50 per cent more than any player has ever earned per week to play football.
