The 37-year-old feels the urge to win even more in the twilight of his career but is understood to feel that may not be possible at Old Trafford next season. The 2021/22 campaign was the fifth in succession in which United failed to win a trophy.
Ronaldo is also understood to be concerned that United is yet to make any improvements to the squad in the current transfer window. Thirteen players have left the club this summer but none have yet arrived.
Ronaldo respects United a lot – especially the fans – and is said to be “in love” with the club, but this coming season will be the first in his career in which he will not play Champions League football if he stays at Old Trafford.
The Portugal international has never played in the Europa League – which United will be in next season – and last played in its predecessor, the UEFA Cup when he was at Sporting Lisbon in the 2002/03 season.
But while Ronaldo is keen to leave, United has taken the stance that he is not for sale and expects him to see out the remainder of his contract, which expires in the summer of 2023.
