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 almost five-fold.
Indeed, the first €1m is already said to have been paid back during his loan spell at the Canary Islands club last season.
Barcelona will pay the club a further €4m this season if Pedri plays at least 25 official matches across all official competitions – with a minimum threshold of 45 minutes to qualify.
Another €2m will be added if and when Pedri is capped by the senior Spain team, having already become a fixture for the Under-21 side.
Furthermore, the remaining clauses would be paid by Pedri renewing his contract at the Blaugrana to fulfil his future at the club.
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.
