The Spaniard, who will become Spurs' most expensive capture when he completes his £26m switch, said that he hopes the Welsh winger remains at White Hart Lane despite Real Madrid's ongoing efforts to sign him.
"I think everybody knows about Gareth Bale. He's a great player. It will be hard to keep him but I hope he stays with Tottenham," Sky Sport News quotes him as saying.
Real are believed to have tabled an £85m bid for Bale, with coach Carlo Ancelotti recently confirming that negotiations between the two clubs are under way.
Bale is reported to have expressed interest in the move.
