Born in
Buenos Aires, Crettaz moved to Spain at early age and joined
Málaga CF's youth setup in 2017, from
Levante UD. He made his senior debut with
the reserves on 25 August 2019, starting in a 4–0
Tercera División away routing of
Alhaurín de la Torre CF. On 16 November 2019, as
Munir was out on international duty, Crettaz made his first team debut by playing the full 90 minutes of a 0–1 loss at
AD Alcorcón in the
Segunda División championship. On 17 August 2021, after being mainly a third-choice option in the main squad, he was loaned to
Primera División RFEF side
CD Badajoz, for one year. On 15 August 2022, Crettaz was transferred to
UD Logroñés also in the third division. On 7 July 2023, after
suffering relegation, he moved to fellow league team
CD Castellón on a two-year deal, and was an undisputed starter as the club
achieved promotion to the second division. On 10 June 2025, despite still remaining a first-choice, Crettaz left the
Orelluts as his contract was due to expire. ==References==
