Ralf Rangnick reportedly has doubts over Cristiano Ronaldo's future at Man United

Manchester United interim manager, Ralf Rangnick reportedly has doubts over footballing superstar, Cristiano Ronaldo spearheading the club's attack next season with the Manchester Evening News claiming that the star could be out of Old Trafford next season.

As per the report, Rangnick's patience is wearing thin with Ronaldo, who has managed one goal in his last 10 games and appears to be drained of confidence for the first time in his career.

Rangnick has not entertained the possibility of dropping Ronaldo due to United's dearth of reliable goalscorers. Striker Edinson Cavani has missed the last five games with a groin problem and scored twice all season, while Marcus Rashford has five goals in four-and-a-half months.

Despite the criticism aimed at him, the 37-year-old is United's top goalscorer this season with 15 goals in all competitions so far, and he remains a key player if the club are to finish in the top-four spots come the end of the season.
