The Red Devils face a huge battle to even qualify for the Champions League in another disappointing season.
Ronaldo has made his frustration clear at his inability to challenge for the Premier League title.
And according to the Mirror, United will no longer stand in his way if he wants to leave Old Trafford this summer.
The 37-year-old would still have one year left on his contract with the Red Devils but they would still let him go.
He only returned last summer and has had a mixed campaign after suffering his worst goal drought in more than a decade.
The Portuguese superstar wants to play in Europe until his final retirement in the coming years.
That, combined with his enormous commercial value, was said to have been the key factor in his comeback.
It didn’t work out as expected, however, with Ole Gunnar Solskjaer sacked halfway through the season.
But Ronaldo is still United’s top scorer, with 15 goals in the 19th campaign of his illustrious career.
The 576,000 EUROS a‑week star is wanted by PSG and Roma if he decides to stop there.
