Santiago Castro, born on 18 September 2004 (age 22), is an Argentinian striker now with Roma, where he wears the number 9 shirt. His market value is around £30m, according to Transfermarkt.
The bulk of his senior career has been shaped at Bologna. Across three league seasons there, Castro made 79 appearances and scored 16 goals, with his best return coming in 2024–25, when he scored eight times in 36 league matches. That is the spell which gives the clearest picture of him as a player: a developing centre-forward with enough output to be taken seriously, but still with plenty of work in the account.
By 2026–27 he was at Roma, where he has made nine Serie A appearances and scored one goal. His career to this point is built mainly on his Bologna years, with Roma the next test rather than the finished answer.
