Chelsea are chasing Real Madrid starlet Pablo Sarabia.

The Daily Express says 17 year-old winger Sarabia, who plays for Real Madrid's B team Castilla, has been watched extensively and could be signed for nothing at the end of the season, as he is currently involved in a contract dispute.

Sarabia is also on Arsenal boss Arsene Wenger's wish list and the Gunners have already made inquiries, while Barcelona boss Pep Guardiola is also keen.
