Diario AS reports that Celta Vigo, Getafe and Rayo Vallecano have all registered interest in the Barcelona academy product, while several Italian clubs and Saudi Arabian sides are also tracking his availability. No agreement has been reached with any club.
Marmol joined Las Palmas in 2023 and has made 105 appearances for the Canary Island club across all competitions, scoring three goals and contributing four assists.
His consistent performances at a club fighting for survival in the second division have elevated his profile considerably, and his release as a free agent makes him an attractive proposition across multiple markets.
The timing of his contract expiry coincides with Las Palmas' promotion play-off campaign, meaning Marmol could end his time at the club without knowing which division they will compete in next season — a situation that adds further complexity to his decision-making.
Forged in Barcelona's La Masia academy before departing without making a senior appearance for the first team, Marmol represents the kind of technically assured, positionally intelligent defender that is in consistently strong demand across the European market.
His age and free-agent status make a deal straightforward to structure for any of the clubs in pursuit.
