Bulgarian striker Dimitar Berbatov wants to leave Tottenham if a suitable offer comes in during the January transfer window, his agent said Monday.

The striker has rediscovered his stunning form for Spurs in recent weeks and fired four goals in the 6-4 win over Reading on Saturday.

And his agent Emil Dantchev claims the player is keen to join a team with greater trophy-winning potential than the north Londoners.

Dantchev told The Sun: "I have already spoken to the Tottenham chairman Daniel Levy and told him that if a club which corresponds to Dimitar's class and ambition comes in with an offer which suits his current club in January, he would like to be allowed to go.

"I would like to stress this is not about money, this is about sporting ambition, nor has it anything to do with the new manager Juande Ramos. Dimitar is perfectly happy with Ramos and the way he is working but after Tottenham's bad start to the season it is unlikely they will have the chance to do something big this season."

Manchester United have been linked with Berbatov in the past, but Spurs have always been firm in stating he is not for sale.

Dantchev added: "Dimitar is OK at Tottenham. I would not say he is happy but his performances for the club are a testament to his commitment to the fans and his team-mates. He has never stopped trying and scoring goals to help the team.

"Fans must understand Dimitar is 27 next month and time is running out for him to play for a club which can match his ambition.

"It is a long-term plan for Spurs. Dimitar wants to fulfil his potential and win trophies now. He would definitely consider a move outside of England, that is not the issue. What matters is a club which matches his ambition and his level, and therefore there are only five or six around Europe. Two clubs outside of England and one from the Premier League are interested in him."
