Odriozola will make his way back to Madrid after a season-long loan deal to Italian side Fiorentina. He joined Fiorentina on 28 August 2021.
In an interview with Odriozola, he expressed how great Fiorentina was to him but he is ready to make his return to the Spanish giants.
“I’m not staying at Fiorentina. My time there was great but I’m now ready for Real Madrid.”
Ordiozola played 25 games with Fiorentina while starting 18 of those games. Throughout his time in Florence, he scored 1 goal and gave 1 assist.
Born in San Sebastián, Basque Country, Odriozola joined Real Sociedad‘s youth setup in 2006, at the age of ten. On 1 September 2013 he made his senior debut with the reserves, starting in a 3–0 Segunda División B away loss against UD Las Palmas Atlético, and in the same month made the first of several appearances in the UEFA Youth League.
Odriozola was definitely promoted to the B-side ahead of the 2014–15 season, and scored his first goal on 6 September 2014 by netting the last in a 3–0 home win against Real Unión. On 25 February 2016, he renewed his contract with Sanse until 2018.
On 16 January 2017, as both Carlos Martínez and Joseba Zaldúa were injured, Odriozola made his first-team – and La Liga – debut by starting in a 2–0 away win against Málaga CF. Up to the end of the campaign, he played in a further 16 competitive matches.
Odriozola renewed his contract until 2022 on 10 June 2017 and was definitively promoted to the senior squad ahead of the 2017–18 season, quickly becoming the first-choice right-back. He scored his first professional goal on 15 February 2018, in the 2–2 draw with FC Red Bull Salzburg in the UEFA Europa League round of 32 at Anoeta Stadium.
On 5 July 2018, Real Madrid reached an agreement with Real Sociedad for the transfer of Odriozola. The fee was reported to be €30 million, plus €5 million of conditional add-ons. He made his debut on 22 September, playing the full 90 minutes in a 1–0 win over RCD Espanyol. Odriozola scored his first league goal on 21 April 2021, scoring the second goal in a 3–0 win over Cádiz.
After playing just five times for Madrid during the first half of 2019–20, in January 2020 he was loaned to Bayern Munich for the remainder of the season. On 23 August 2020, Bayern won the 2019–20 UEFA Champions League.
