Denil Castillo (born 24 March 2004, age 22) is an Ecuadorian central defensive midfielder whose senior career is already tied closely to FC Midtjylland. Wearing number 21, he has made 52 league appearances for the Danish club across three seasons, scoring four times.
His strongest league campaign came in 2025-2026, when he scored four goals in 26 appearances. That gave some substance to his role beyond the usual screening work, though Midtjylland remains the clear centre of the story rather than a staging post.
Castillo has stayed involved in 2026-2027, with 19 appearances for FC Midtjylland across all competitions, including league, European qualifiers and Europa League matches. He has also represented Ecuador this season with one appearance in South American World Cup qualifying.
His current market value is around £3m, according to Transfermarkt. At this stage, his career is a developing one, but it is being shaped very plainly by regular first-team football at FC Midtjylland.
