[24] Olmo made his first start for Leipzig on 9 February 2020, in a game against Bayern Munich that ended as a goalless draw, coming off for Patrik Schick in the 69th minute.

[32] On 9 August 2024, Olmo returned to his youth career club Barcelona, signing a six-year contract in a deal reportedly worth in the region of €60 million.

[33][34] On 27 August 2024, after missing the games against Valencia and Athletic Bilbao as he was unable to be registered due to salary-cap issues, Olmo made his debut.

[38] Olmo was part of the Spanish squad at the 2015 European Under-17 Championship in Bulgaria; he netted in the penalty shoot-out as they were eliminated by Germany in the quarter-finals, but then had his attempt saved by Will Huffer as Spain lost to England by the same means in a play-off for that year's World Cup for the category.

[39] Towards the end of 2017, Dinamo Zagreb director Tomislav Svetina said that the club was doing all it could to get the teenager Croatian citizenship as Olmo himself showed a desire to switch to Croatia at the international level.
