Marc Guiu's signed Chelsea F.C. shirt from the 2024-2025 season carries the number 38, in a size L. Beckett graded the signature 10 out of 10, the first example of Guiu's autograph it has certified, confirmable in Beckett's own database.

Chelsea's 2024-25 home kit in blue, number 38

Guiu signed this blue Chelsea home shirt from the 2024-25 season, his signature placed on the number on the back. Nike manufactured the shirt, which remains today in mint condition, unmarked beyond that signature. That one authenticated signature is what gives this shirt its worth: a genuine mark from him, placed on a shirt in Chelsea's blue home colours for that season, plainly his to claim.

Authentication by Beckett

Beckett issued a certificate of authenticity for this signed shirt, the paperwork that accompanies it. The authenticator graded the signature 10 out of 10. An iridescent hologram disc sticker, also from Beckett, is fixed directly to this shirt, a separate mark of authentication from the certificate.

Signed in London, September 2024

This shirt was signed in London, England on 6 September 2024, the date and place behind this signature. The signing photograph shows a young man leaning out of a car window, smiling, mid-motion, part of that same moment. Walkouts assigned this shirt its own proof code, 24MGP20018438, and keeps that record entirely separate from Beckett's certificate, specific to this signature and no other.

Premier League debut

Guiu made his Premier League debut for Chelsea on 18 August 2024, as a substitute against Manchester City. The appearance followed his La Liga debut for Barcelona on 22 October 2023, when he scored with his second touch to secure a 1-0 win over Athletic Bilbao, the youngest and fastest debutant to score for Barcelona in that competition. He had arrived from Barcelona on 1 July 2024, on a five-year contract.

Beckett certificate and signing video

You receive the authenticated signature, carried on the shirt, with a Beckett certificate of authenticity. Photographs of the signing and the video of the signing come with it, the video sent to you without a watermark after purchase.
