Tottenham chief Fabio Paratici has confirmed Arnaut Danjuma's loan deal carries a permanent option.
Danjuma signed for Spurs this week on-loan to the end of the season.
Paratici said, "We have the option to buy and will see what happens in the next five months.
I think Danjuma will be very important, he can help us.
"He's a player who's been on the verge of moving to a big club in every transfer window for two or three years."
