Ramos refused to be drawn on whether Jonathan Woodgate is poised to move to White Hart Lane.
There have been reports that the Middlesbrough defender has secured a three-and-a-half-year deal and passed a medical with Spurs, who were vying with Newcastle for the England man's signature.
Brazilian full-back Gilberto has also reported to be in London ahead of a move from Hertha Berlin.
But Ramos said: "My mind is on this game, not what with what is happening elsewhere. This is not the time to be talking about perhaps reinforcing the squad."
