Cristiano Ronaldo has told Manchester United he wishes to leave this summer amid concerns he will be unable to compete for the biggest trophies at the club.

United insist he is not for sale and have underlined that he is under contract for another year, although new boss Erik ten Hag is indifferent to whether the Portuguese stays, hopeful that his departure would help fund other transfers.

Ronaldo was staggered by United appointing three managers in quick succession after the sacking of Ole Gunnar Solskjaer in November, growing frustrated by the club's demise and concerned at the lack of progress since Solskjaer's departure.

His agent, Jorge Mendes, has been talking to clubs such as Bayern Munich, Chelsea and Napoli over recent weeks to test whether there is a market for his client but no agreement is in place as it stands.
