Sunderland AFC have bolstered their striking options by landing 19‑year‑old Spanish forward Marc Guiu from Chelsea on a season‑long loan deal. Crucially, the agreement contains no option to buy, highlighting that Chelsea still view Guiu as part of their long‑term project.
Transfer Details
- Type of deal: Straight loan from Chelsea to Sunderland for the 2025‑26 season
- No purchase clause: Sunderland cannot buy Guiu at the end of the loan
- Wages covered: Sunderland will pay Guiu’s estimated £50,000/week salary, costing around £2.35 million over the season
- Medical scheduled in Wearside before the club confirms completion
Player Profile & Background
- Full name: Marc Guiu Paz, born 4 January 2006, in Granollers, Catalonia
- Position & Physicality: A classic “number 9” centre‑forward – tall (1.89 m), strong, with good aerial ability and fierce work‑rate
- Youth pedigree: Developed through Barcelona’s famed La Masia and made a sensational La Liga debut in October 2023, scoring a winner just 33 seconds after coming on—making him Barça’s youngest ever scorer on debut
- Chelsea arrival: Signed in July 2024 for around £5–£6 million on a five‑year deal, with strong belief from coach Enzo Maresca that he has a key role in Chelsea’s future

On‑Field Impact & Sunderland Fit
- 2024–25 snapshot: 16 first-team appearances at Chelsea—including 9 in the Conference League—yielded six goals, all in Europe; only 3 Premier League outings
- Playing style: Central poacher with keen positional sense, strong pressing, and aerial threat—adding dimension to Sunderland’s existing strikers Mayenda and Isidor
- Strategic purpose: Sunderland view him as complementary depth rather than a direct replacement—providing physical presence and a different tactical option up front
Significance for All Parties
- Chelsea retain control and signal faith in Guiu’s development by preferring a dry loan to Premier League opposition rather than a club like Pisa
- Sunderland continue a proactive recruitment drive following promotion, making Guiu their ninth summer signing as they aim to stay competitive in the Premier League
- Guiu himself gets a chance to earn consistent top-flight minutes in a highly competitive environment, pushing his development forward
