Tottenham are already eyeing a replacement for Welsh winger Gareth Bale.
The veteran has spent the season at the London club on loan from Real Madrid.
Bale is, however, set to return to the Santiago Bernabeu club when his loan deal expires at the end of the season.
According to Sky Sports, Spurs are now looking at Stuttgart forward Nicholas Gonzalez as a possible replacement.
Bale himself stated in recent days that he is planning on a return to Real, and Spurs see 22-year-old Gonzalez as an exciting and affordable alternative.
Stuttgart want a fee of around €30 million for the attacker, who has six goals and two assists in 15 league games in Germany this term.
