Romelu Lukaku must consider quitting Everton to join Manchester United or Bayern Munich, according to his father.

The striker has delivered a blow to the Merseysiders by making clear his ambition to play in the Champions League next season.

The Belgium international, who is rated in the “world class” bracket by club manager Roberto Martinez, says the “next step” in his career path is to perform in Europe’s leading club competition.

Lukaku’s father Roger is convinced that it’s time for his son to move to United or Bayern Munich.

“He’s ready,” Lukaku Sr. told Het Laatste Nieuws‏. “I see that there is interest from Atletico Madrid, Bayern Munich, Juventus, Chelsea and Manchester United.

“I think he must choose Manchester United or Bayern Munich. Manchester United is a team under construction with no real focus.”

However, Lukaku senior, a former professional goalkeeper, believes his 22-year-old son should join Bayern only on one condition.

“Bayern Munich is a machine where he can rotate well,” said . “The only condition is if Robert Lewandowski leaves.”

Everton’s £28million record signing is in his third season at Goodison Park and, since arriving in English football in an £18million move to Chelsea from Anderlecht in 2009, has scored a highly impressive 78 goals in 156 club matches.
