Tottenham have confirmed Nabil Bentaleb has been sold to Schalke.
Bentaleb will become a Schalke player on a permanent basis at the end of his season-long loan from Tottenham.
Schalke stated the deal would run until 2021. The fee involved is undisclosed.
Bentaleb leaves Tottenham after 66 appearances and one goal.
Tottenham said in a statement: "We have reached agreement with FC Schalke 04 for the permanent transfer of Nabil Bentaleb this summer."
Moving away from the Premier League has given Bentaleb's career added impetus.
"When I came to Schalke in the summer, my aim was to play as much as possible and persuade the club to make the transfer permanent," he said on Schalke's website.
"Things have worked out brilliantly and I am thrilled.
"It is great to have the feeling that you are trusted by the club: the coaching staff, my team-mates, the higher-ups and everyone here have made it really easy to feel at home at S04. I am very happy to be a part of this team."
