Ramos cannot guarantee that Berbatov will stay when the January transfer window opens but he wants the striker in his plans.
"He made a great contribution against Reading. Magnificent," said the Spurs head coach. "He is a very valuable player for us.
"But I cannot assure that he is going to stay at the club because the chairman has to decide that.
"The chairman knows I want Berbatov to stay. If it was up to me we would not lose him but there are different circumstances and factors that we have to take into account such as the player's opinion and feelings.
"If it was up to me he would continue with us."
