Spurs coach Juande Ramos said yesterday he wouldn't keep Berbatov at White Hart Lane against his will and the player's brother admits he's desperate to move to Old Trafford.
Asen Berbatov told The Sun: "In my opinion, Tottenham are OK. In Manchester, though, things will be better - much better.
"If United really want him, maybe he should go. I think it is his time to go. There is nothing more to do at Spurs. Dimitar is under-performing. He is feeling very good physically. But as regards everything else, it is a big disappointment - especially with the team dropping in the league.
"He doesn't feel very good emotionally. This is the reason that the games are not going well. My brother is like this. When the team has bad form, he goes into standby mode.
"He shares his secrets about everything, yet still we don't talk about the new coach. Sometimes he finds it better to withdraw from things and collect his thoughts.
"Nothing is changed. Everyone is looking for a way to escape from this situation.
"My brother is at this moment feeling depressed. The problem is he doesn't score and the team goes bad. The rumours about him do not bother him.
"I think he will stay in England. He likes the style of football. He has outgrown Spurs. He needs to find a bigger club. I think this next season he will go to a bigger club.
"Next season he will be in a club playing in the Champions League."
