Lucas Rosa, born on 3 April 2000 (age 26), is a Brazilian right-back with Ajax. His current market value is around £2.5m, according to Transfermarkt.
His senior career has been shaped most clearly by Real Valladolid. Across three seasons there, he made 73 league appearances and scored once, with his busiest campaign coming in 2023-2024, when he played 35 league matches. That spell did most of the work in establishing him as a first-team professional rather than just another young full-back passing through the system.
Rosa is now at Ajax and remained firmly involved in 2025-2026. He made 27 Eredivisie appearances, along with outings in the KNVB Beker, European play-offs, Conference League qualifying and the Champions League. Across all competitions for Ajax that season, he reached 35 appearances.
His career to this point is a straightforward one: a Brazilian full-back whose main grounding came at Real Valladolid, followed by a regular role at Ajax in his mid-twenties.
