Bartosz Mrozek

Bartosz Mrozek (born 23 February 2000) is a Polish professional footballer who plays as a goalkeeper for club Udinese.

Club career Youth career Starting his youth career with several Silesian clubs, Mrozek joined Lech Poznań's youth setup in mid-2014. In 2017, he trialed at English club Manchester United and drew interest from Crystal Palace, before making his first senior appearances for Lech's reserve team that year.

On 12 May 2022, Mrozek joined Ekstraklasa club Stal Mielec on an emergency loan until the end of the season, after Stal's goalkeepers Rafał Strączek and Damian Primel suffered injuries ruling them out for the remainder of the campaign. He made his Ekstraklasa debut three days later, on 15 May 2022, in a 1–1 home draw against Śląsk Wrocław which secured his team's survival from relegation.

On 16 June 2022, he extended his contract with Lech until June 2024 and was sent on loan to Stal again, until the end of the season, with an option to buy. Mrozek remained a starter for Stal throughout the entire campaign, keeping 12 clean sheets in 34 league matches. After Stal made use of their buy option at the end of the season, Lech immediately exercised their buy-back clause to bring Mrozek back to the club on a new three-year deal.

First-team breakthrough, domestic success Having started the 2023–24 campaign as back-up to Filip Bednarek, Mrozek eventually earned a regular spot in Lech's line-up. He went on to keep 11 clean sheets in 31 Ekstraklasa appearances, as Lech finished the season in 5th.

On 8 November 2024, he signed a contract extension with Lech, keeping him at the club until June 2028. Mrozek started and played all 34 games of the 2024–25 league campaign, keeping 14 clean sheets, as Lech won their ninth Ekstraklasa title. For his efforts, he was named the Ekstraklasa Goalkeeper of the Season.

Mrozek continued to be a mainstay in Niels Frederiksen's side, as he started 53 out of 54 of Lech's games throughout the 2025–26 season that ended in a successful title defence; he missed a single league game in April 2026 after being bitten by a dog.

Following the arrival of Mateusz Lis in the summer of 2026, Mrozek lost his spot in the starting line-up. In total, he made 121 appearances for Lech's senior team, keeping 42 clean sheets.

Udinese On 28 August 2026, Mrozek moved to Serie A side Udinese for a reported fee of €1.5 million.

International career A youth international for Poland, Mrozek received his first call-up to the Poland national team for UEFA Nations League matches against Scotland and Croatia in September 2024.

Personal life His father Piotr is a football manager and coach, and a former player.
