Real Betis are already discussing keeping hold of Charly Musonda.
The young Belgian has been in sensational form for Chelsea since joining in Betis in January.
Musonda is on a straight loan at Betis to June.
But El Desmarque says such has been his impact, that Betis are eager to sign the teen outright.
The Seville club would also be keen to extend Musonda's loan into next season.
