He took over as Warta Poznań's manager in June 2019 with the stated mission of avoiding the club's relegation from I liga, the second tier of Polish football.[1] To the surprise of many pundits, with Tworek in charge, Warta returned to the Ekstraklasa in 2020, after being absent for 25 years.[2] In their first season back in the top tier, Tworek led Warta to a fifth-place finish, the club's best result since 1947.[3]
However, Warta's next campaign in Ekstraklasa saw them struggling from the beginning, as they only managed one win and eight points in thirteen games. Due to this poor start, Tworek was dismissed on 2 November 2021.[4]
On 9 March 2022, he was announced as the new manager of another Ekstraklasa side Śląsk Wrocław.[5] With Tworek in charge, Śląsk managed one win and six draws in ten league games. Despite avoiding relegation, he was relieved of his duties on 25 May 2022.[6]
