I don't think Ronaldo will be staying after this season in Manchester United, it is time United start searching for a suitable replacement.
Ronaldo is not a problem to Manchester United, they don't really depend on him, so if he likes he stays or leave Manchester United won't be affected. Manchester United are doing well in performance presently not even because of Ronaldo's. Ronaldo has only score 1 goal for Manchester United in the Europa League and has not score any goal in the premier league this season. Manchester United has other good stars who are contributing alot for the club to come out best this season.
Ronaldo surely was not the problem at Manchester united and is not the problem, we shouldn’t point fingers at him as the cause of the overall failure of the club. The problem of the team was generally lack of team work, togetherness, good tactics and presence of average performing players who were not even ready to play. I can’t forget that Ronaldo was the one that put Manchester United on sixth position last season helping them qualify to play European football this season.
