Saul Niguez's new nine-year contract with Atletico Madrid reportedly includes a release clause of £130m.
It was announced on Saturday that the 22-year-old, who has been linked with a move to Barcelona in recent weeks, had signed a new long-term contract with Atletico until the summer of 2026.
There was no mention of the midfielder's release clause when the terms of the contract were announced, but according to Marca, it will take £130m for interested clubs to free the Spaniard from his new deal.
Saul, who has scored 22 times in 136 appearances for Atletico over the last three seasons, netted five times for Spain Under-21s this summer as La Roja reached the final of the Under-21 European Championships in Poland.
Manchester United and Arsenal have previously been credited with an interest in the versatile midfielder.
