Barcelona are watching Atletico Madrid starlets Koke and Jorge Pulido.
The two Spain U19 internationals come off contract in June and AS says Atletico have yet to make any move to open talks about extending their stays.
Barca are aware of the situation and have already been in touch with midfielder Koke (19) and defender Pulido (19) to register their interest.
Atletico remain calm, however, as the contracts for both players include the option to unilaterally automatically extend in June.
