Giovani Lo Celso has completed his loan move to Villarreal.
The midfielder flew to Spain on Friday night ahead of joining the club on a season-long loan.
There is no option to buy in the deal and the 26-year-old can be recalled by Tottenham in January.
Lo Celso returns to Villarreal after spending the second half of last season with Unai Emery's side.
He scored one goal in 22 appearances, but seemed more settled after struggling to find his feet in North London.
