Lucas Rosa, born on 3 April 2000 (age 26), is a Brazilian right-back whose senior career has so far been shaped mainly by Real Valladolid. His current market value is around £2.5m, according to Transfermarkt.
Valladolid gave his career its substance. Across three seasons he made 73 league appearances, scoring once, with his busiest and most productive campaign coming in 2023-2024 when he played 35 league matches and got his league goal. For a developing full-back, that spell was less about decoration than accumulation: regular football, responsibility, and enough visibility to move him on.
He is now with Ajax, where he has remained involved rather than drifting to the margins. In 2025-2026 he has made 33 appearances in all competitions, including 27 in the Eredivisie, three in the Champions League, two in the European play-offs and one in the KNVB Beker. He has not scored, which is hardly the central measure of his job.
Rosa’s career to this point is straightforward enough: a Brazilian defender whose strongest body of work came at Real Valladolid, followed by a regular first-team role at Ajax in 2025-2026.
