The 17-year-old joined the Blaugrana in a €5m transfer from Las Palmas last summer and is widely regarded as one of the best youth products in Spanish football, but that fee could rise five-fold.
The details are outlined by Marca, who quote Las Palmas president Miguel Ángel Ramírez, who has said: “The figure could go up to around €25m in the coming years.”
It is said by the report that the first €250k clause is close to being fulfilled with the minimum number of games objective fulfilled, whilst multiple other attainable clauses are said to be within reach.
The teenage star – whose full name is Pedro González López – starred for Las Palmas last campaign and netted four goals for Pepe Mel’s side, alongside providing six assists.
As highlighted by a report in Marca last month, the teenager had to take a taxi home from the Camp Nou after scoring in his Champions League debut against Ferencvaros – his only goal for the club in eight appearances to date.
A month younger than Barcelona teenage forward Ansu Fati, he has risen through the ranks of the Spanish youth teams and now is rated among the best teenagers in European football.
