Malaga wing-back Sergio has Spain's biggest clubs chasing his signature.
Real Madrid, Barcelona and Atletico Madrid are all pursuing the promising 19 year-old, who is starring with Malaga B.
Sergio is off contract in June and Malaga sources say Barca are favourites to snap him up.
A clause in his deal states he will be automatically handed a new 12 month contract by Malaga should he complete 20 games for the reserves. Last week Sergio played game number 19.
