AS Saint-Étienne forward Lucas Stassin is on the verge of joining La Liga side Sevilla FC on a loan deal with an option to buy, according to reports from outlets including L’Équipe, Foot Mercato, and DHnet. With less than 24 hours remaining in the French summer transfer window, negotiations are centering on a 2.5 million euro loan fee paired with a 25 million euro purchase option.
The 21-year-old Belgian international was conspicuously absent from the matchday squad as AS Saint-Étienne faced Dijon FCO in Ligue 2 action. Having secured a “bon de sortie” (permission to leave) earlier in the window following Les Verts’ failure to win promotion back to Ligue 1, Stassin has struggled to nail down a permanent suitor until Sevilla made him an explicit priority. According to transfer specialist Sacha Tavolieri, corroborated by Onze Mondial and relayed by regional outlet MadeInFoot, the deal is advancing rapidly toward a formal agreement before the deadline.
Fantasy & Market Impact
- La Liga Fantasy Upside: Stassin’s impending arrival in Andalusia injects a fresh, physically imposing profile into Sevilla’s attacking depth chart, though immediate starting minutes will require displacing veteran options.
- Ligue 2 Market Shift: AS Saint-Étienne loses a marquee offensive asset under contract until 2029, forcing manager Olivier Dall’Oglio to lean heavily on alternate target men for the remainder of the campaign.
- Valuation Trajectory: The proposed 25 million euro purchase option signals significant faith from Sevilla’s front office in the young Belgian’s resale value and long-term ceiling.
The Financial Mechanics of the Sevilla Move
The structure of the agreement highlights a cautious yet ambitious approach from the Spanish club. By utilizing a paid loan structure set at 2.5 million euros, Sevilla mitigates immediate financial exposure while securing exclusive rights to evaluate the striker across a grueling La Liga calendar. Under contract in the Forez until 2029, Stassin carries substantial long-term value, which explains why AS Saint-Étienne’s hierarchy fought to install a robust 25 million euro purchase option.
But the tape and the balance sheets tell complementary stories. Following the disappointment of missing out on an immediate return to France’s top flight, Les Verts needed to rationalize their wage bill and monetize assets that retained elite market appeal. Stassin, capped at the international level for Belgium, fits the profile of a high-ceiling project that top-tier European sporting directors target in the final hours of a window.

For Saint-Étienne, turning the page on the Stassin chapter opens immediate roster flexibility as they recalibrate their promotion ambitions.
