Lucas Stassin heads to Sevilla: loan with purchase option

Lucas Stassin (21) is on the verge of swapping Saint-Étienne for Sevilla. According to L’Équipe, the Belgian forward arrived in the Forez in the summer of 2024 and is now nearing an exit, after he was even allowed to travel to Andalusia to push talks with the LaLiga club.

Loan deal and option

The report says the move is set up as a paid loan worth €2.5m, with a non-compulsory purchase option for €25m. Sevilla would have until next June to decide whether to trigger that option. If Stassin stays at Sevilla, Saint-Étienne would also receive 20% of any future resale profit.

Before the transfer, Saint-Étienne secured the player’s value: the article notes Stassin has extended his contract by one season, meaning he is now tied through June 2029. It also highlights that he was not in the trip to Dijon on Monday night, which fits the idea that the negotiations are already well advanced.

Why it matters for Sevilla

For Sevilla, bringing in a young striker through a structured arrangement—first on loan, then with time to evaluate—offers a more measured way to reinforce their attack. For Stassin, it would be a direct chance to take a step up in Spain’s top flight.

L’Équipe adds a final detail: Sevilla were also very interested in another young forward, Deivid Washington (Chelsea U21).
