The 37-year-old feels the urge to win more in the twilight of his career, but may not be able to do that at Old United.

United are yet to make any additions to their squad in the current transfer window, and that is something thatRonaldo is worried about.

The player is said to be very fond of the club and respects the fans a lot.

They want to sign Frenkie de Jong from Barcelona, and they also want to sign Lisandro Martinez from Amsterdam.

He was frustrated as the team failed to finish in the top six.
