Former Manchester United midfielder Kleberson believes Romelu Lukaku should leave this summer.
Kleberson can understand Lukaku touting himself to Inter Milan.
He told Your-promotional-code.co.uk: "If Romelu Lukaku is to leave the club, it will be a big loss for Manchester United. I'm a big fan of Lukaku, he's a great player. When you think about coaching, everyone wants to take him, he is a very good player to have in the squad. Whether he starts games or is on the bench, he will always help the team to score goals.
"If he starts up top, you can play off him and help the midfield and other forwards to score more goals. He can also drift out wide and cause problems for defenders there, he killed Brazil in the game at the World Cup from doing this and he's very unpredictable.
"I understand if Lukaku wants to leave and play more games. He didn't start too many games for Man United last season. Strikers survive on goals and statistics, it's tough. The season changed so quickly for him, if players prepare mentally in the preseason, he may find his feet again. I hope he decides to stay at Manchester United for one more year and proves his worth."
