Dembele started his professional career with Grimsby Town before spending four successful seasons with Peterborough United.

Following this, Dembele also spent two seasons at Bournemouth in the Championship and Premier League, with spells then at Auxerre in Ligue 1 and more recently Birmingham City.

Having signed for the U's in the summer of 2024, Siriki made 26 appearances in his first season at the Club and his tricky wing play continues to cause defenders problems at this level.
