Former Tottenham midfielder Yves Bissouma has joined Ajax on an initial deal that runs until the end of the season.
The defensive midfielder, 30, was out of contract following his release from Spurs in June.
Bissouma has agreed a deal until the end of the season, but BBC Sport understands his contract includes the option of a further 12 months.
Ajax technical director Jordi Cruyff said they had been in talks with Bissouma since August.
Cruyff told the club website: “We have brought in an experienced player who knows what it takes to perform at the highest level. He is capable of playing in several positions, and we hope he will be available for selection as soon as possible.”
