Lucas Rosa, born 3 April 2000 (age 26), is a Brazilian right-back with Ajax. His market value is around £2.5m, according to Transfermarkt.
The main body of his senior football has come with Real Valladolid, where he made 73 league appearances across three seasons and scored once. His fullest campaign there was 2023–24, with 35 league appearances and a goal, giving him a proper run rather than the usual stop-start existence of a young full-back abroad.
At Ajax in 2026–27, Rosa has made 17 appearances across all competitions, including Eredivisie matches, European play-offs, Conference League qualifiers and the Conference League itself. It is still a developing chapter beside the Valladolid spell, which remains the clearest reference point in his career so far.
