Tottenham midfielder Nabil Bentaleb is close to triggering a £16million permanent move to Schalke.
The 21-year-old is on a season-long loan at the Bundesliga club and his 20th appearance for them, due to be against Cologne on Sunday, would trigger a clause in the deal to make the move permanent.
Bentaleb has scored four goals for Schalke this season.
Bentaleb was a regular under previous boss Tim Sherwood and still has more than three years of his contract to run.
