Tottenham manager Andre Villas-Boas has dismissed talk of Danny Rose joining Sunderland on a permanent basis at the end of his current loan deal.
The 22-year-old made the move to Wearside in August until the end of the season, and has quickly become fan favourite at the Stadium of Light.
Speculation is rife that Martin O'Neill might try to prise the England Under-21 international away from Spurs next summer. But Villas-Boas has rejected those claims.
Speaking after his side's 2-1 victory over sunderland on Saturday, he said: "Permanent is completely impossible because we have big expectations for the player for the future.
"There is a high possibility that his loan spell will continue, but we appreciate what he has been doing over here.
"It's been a massive experience. He has been extremely well managed. He's been man of the match a couple of times, and we can't give away a player of his qualities."
Rose has made 16 appearances for Sunderland in the current campaign so far.
