Born in Bilbao, Spain, Guerrero started his career at Málaga, before joining Real Madrid in 2017.[3][4] Despite being a midfielder, he has amassed an impressive goal tally for Los Blancos youth teams, notable scoring in eight consecutive games in the 2020/21 season.[4][5]
Due to his father's legendary status at Athletic Bilbao, Guerrero has found himself constantly linked with the Biscay club.[6][7][8][9][10] In October 2021, he was included in The Guardian's "Next Generation" list for 2021 - highlighting the best young players in the world.[11]
Guerrero scored his first senior goal on 12 February 2023, netting the Azules' equalizer in a 1–1 draw at FC Barcelona Atlètic.[14] He scored a further three times for the club as they achieved promotion to Segunda División.
Loan to Roma
In July 2023, Real Madrid sent Guerrero on loan with an option-to-buy to Serie A club Roma's youth sector.[15] In January 2024, after failing to break into the first team under José Mourinho, Guerrero's loan was terminated.[16]
Alavés
On 11 January 2024, after his loan spell at Roma was cancelled, Guerrero left Real Madrid and signed a contract until 2025 with Basque club Alavés, initially joining the side's B team, competing in the Segunda Federación.[17] Real Madrid reportedly kept 50% of his economic rights.[18]
Second loan to Amorebieta
On 30 August 2024, Guerrero returned to Amorebieta on loan from Alavés.[19]
International career
Guerrero has represented Spain at under-15, under-16 and under-18 level.[1] His under-18 international career got off to an explosive start; having scored a hat-trick against Turkey, he followed this up with a goal against Romania.[20]
