Cristiano Ronaldo 'asks to leave' Manchester United amid interest from Chelsea and Bayern Munich

The 37-year-old, who had played in Europe's top tier competition in 19 consecutive seasons, is still determined to compete with the continent's biggest clubs. 

Manchester United missed out on Champions League qualification after a dismal domestic campaign which saw the club finish sixth.

The Portugal international still believes he has "three or four" years left at the highest level and would like to spend them at a club where he would be capable of adding to his long list of team and individual accolades, according to a report in The Times.
