Justin de Haas is a Dutch central defender, born on 1 February 2000 (age 26), now with Valencia. At a commanding 6ft 4in (1.94m), he has the frame for the position, though his career so far has been shaped less by profile than by steady senior football.
Famalicao has been the main body of his work. Across three seasons with the Portuguese club, de Haas made 82 league appearances and scored eight league goals, a useful return for a centre-back. His most productive campaign came in 2025–26, when he scored five times in 31 league matches.
He was linked with a move to Celtic in July 2025 while at Valencia. His market value is around £2.5m, according to Transfermarkt.
De Haas remains an established professional rather than a headline name. His career to this point is best understood through his Famalicao spell, with Valencia and any Celtic interest sitting around that central run of regular football.
