John Barnes has told to stay at this summer, claiming he won’t find a better club.

‘He’s not going to go to a side that’s better than Manchester United, even if they were in the .
‘He may want to go to America, but that’s up to him. He’s been fantastic over the years, one of the best ever to play. It’s just a question of whether he thinks he has enough to offer.

On Monday, new manager Erik ten Hag replied ‘of course’ when asked whether Ronaldo was in his plans for next season.
