Belgium boss Roberto Martinez says "it is clear" that Romelu Lukaku has to leave Manchester United this summer.
Martinez, who worked with Lukaku at Everton, feels both parties may benefit if the striker secures a transfer away from Old Trafford.
The 26-year-old has been heavily linked with Serie A giants Inter Milan - who are rebuilding their side under new coach Antonio Conte.
"It is clear that he has to leave Manchester United," Martinez told Belgian newspaper Het Laatste Nieuws.
"It would be a good thing for both parties. It is now important that Romelu finds the right club."
