Tottenham have made a huge bid for Real Betis midfielder Giovani Lo Celso.
BBC Sport reports Tottenham have made a bid of about 60m euros (£53m) for Lo Celso.
But Lo Celso has a 100m euro (£88m) release clause and it is understood Betis want to sell him for a fee closer to that amount.
Spurs will face competition for the 23-year-old Argentine with other Premier League clubs interested.
The Londoners have not signed a player since January 2018 when they paid Paris St-Germain £23m for winger Lucas Moura.
Tottenham's record signing is Davinson Sanchez - they spent £42m on Ajax's Colombia centre-back in August 2017.
