Tottenham are nervous over Juventus' interest in Christian Eriksen.
The Daily Mail says Spurs want to tie Eriksen down to a new-and-improved deal.
Eriksen, who has scored six goals and assisted six in the Premier League this season, has two years left on his £70,000-a-week contract.
Spurs are set to open talks with the 25-year-old attacker and it comes amid talk of interest in Eriksen from Italy's Juventus.
He has played 23 times in the Premier League this season - featuring in every game for Mauricio Pochettino's side.
