The striker will continue his development at the newly-promoted club to build on a positive debut season at Chelsea.

Guiu made 16 appearances for Chelsea last season after arriving from Barcelona and struck six goals during our successful Conference League campaign.

Three of those came in a victory over Shamrock Rovers, a feat which resulted in Guiu becoming the second-youngest player (18 years and 350 days old) to net a hat-trick for Chelsea.

The 19-year-old also featured for the Blues at the Club World Cup, playing twice as we went on to be crowned world champions.

We look forward to supporting and monitoring Marc’s development throughout his loan at the Stadium of Light.

Good luck, Marc!
