Aljaz Strajnar

Aljaž Strajnar (born 16 August 2007) is a Slovenian professional footballer who plays as a goalkeeper for Serie A club Monza.

Strajnar previously played for Mura, where he made his senior debut in the Prva Liga aged 17. He is a Slovenia youth international since 2021.

Strajnar was born in Ljubljana on 16 August 2007. He comes from a footballing family. His father, Janez Strajnar, was a goalkeeper who made 421 appearances in the Slovenian top flight and represented Slovenia once, while his older brother Mark Strajnar [sl] also became a professional footballer. Aljaž and Mark grew up in Domžale, where their father had settled after his playing career.

Strajnar began playing football at the age of five with Olimpija Ljubljana, before joining Domžale after entering primary school. During the 2022–23 UEFA Youth League, he made his debut in the competition for Domžale in their two-legged tie against Young Boys. In July 2023, Strajnar joined Mura, initially playing in the club's youth teams. During the 2024–25 season he played in the NextGen League before being promoted to the senior squad.

Strajnar made his PrvaLiga debut for Mura on 28 April 2025 against Bravo. His appearance came 5,819 days after his father Janez had made his final appearance in the Slovenian top flight, also making Aljaž the first member of the Strajnar family to appear in the competition since his father. He was subsequently given further opportunities in the Mura first team. In May 2025, Strajnar started two league matches due to first-choice goalkeeper Florijan Raduha being unavailable through a minor injury.

Strajnar ended his time at Mura with ten appearances in the Prva Liga.

On 19 August 2025, Strajnar moved to Italian club Monza on a contract running until 30 June 2029. The transfer was reported to be worth around €300,000, with the final amount potentially increasing through bonuses. Mura also retained a percentage of any future transfer. Monza stated that Strajnar would initially be involved with their Primavera youth side while also training with the senior team.

Strajnar has represented Slovenia at under-15, under-16, under-17, under-18, and under-19 level. He made his under-15 debut in 2021, followed by appearances for the under-16 team in 2022, the under-17 team in 2023, the under-18 team in 2024 and the under-19 team in 2025. As of August 2026, he had made 12 youth international appearances for Slovenia across the five age groups.
