Tottenham have made midfielder Giovani Lo Celso's loan move from Real Betis permanent, completing a £27.2m transfer.
The Argentina international has signed a deal until 2025.
A Spurs statement read: "We are delighted to announce that we have exercised the option to convert the loan of Giovani Lo Celso to a permanent transfer.
"The midfielder has produced impressive performances after establishing himself in the team following a hip injury which restricted his playing time in the early part of his loan at the club."
