Ramos said: "Obviously we have been concentrating on the game and since Friday our minds have been on the game.
"For the moment Berbatov is a Spurs player. We are happy with him, he is part of the Spurs squad and there is nothing to say about it, I don't have any comment to make on it."
Berbatov was introduced as a 65th-minute substitute, but Ramos insisted the decision to start the match with him on the bench had nothing to do with a probable transfer to Manchester United.
"However, as Middlesbrough tired in the game we thought it might be the right moment in the game to throw on Berbatov."
Asked if he wanted Berbatov to stay, he replied: "Of course, I love great players."
