Thomas Bertels (born 5 November 1986) is a German former professional footballer[2] who played either as a left-back or as a left midfielder, and current manager of Schalke 04's U17 squad.
In January 2019, Bertels retired as a professional player.[3]
In July 2018, Bertels became co-coach of SC Paderborn's U19s while still playing for the club's reserve team. In 2019, he became coach of Paderborn U16s[4] while playing for lower-league team TuS Ehringhausen.[5]
On 24 February 2022, Bertels took over Paderborn's reserve team in the Oberliga Westfalen, succeeding Michél Kniat, who moved to third-division club SC Verl.[6] During this time, he played for lower-league side VfB Schloß Holte.[6] After promotion to the Regionalliga West, he left Paderborn a year before the end of his contract to take over Schalke 04's U17s.[7]
