The Bulgarian, 26, scored 23 times in his debut campaign for Spurs in 2006-07 and was rumoured to have attracted a host of suitors in the summer.

Manchester United manager Sir Alex Ferguson is reportedly keen on another move for Berbatov in January, but Ramos insists the former Bayer Leverkusen hitman will be staying in north London for the time being.

"There is no chance Berbatov will leave in January. On the contrary, we need Berbatov because if we want to reach our objectives we need a player of his class," he told The Sun.

"I can only tell you that Berbatov is a great player and with so little money it's impossible to take him.

"They have to put a lot of money on the table and many good players to compensate for the quality of Berbatov.

"Dimitar for us is a player who is not for sale. It will be very difficult, very complicated for anyone to take him."

Berbatov expressed his desire to remain at the north London club.

He told the Daily Telegraph: "It's a pleasure and an honour to play for Tottenham and I enjoy myself here. I love everyone who loves Tottenham and I see the passion of our fans.

"It doesn't matter if we are winning or losing, they are still behind us and that's what I really appreciate.

"When we go on to the pitch and we hear them applauding and cheering the team, it gives us a lift and makes us determined to do well."
