Jeremy Toljan, born in Stuttgart on 8 August 1994 (age 32), is a German defender whose career has settled most firmly at Sassuolo. He had his early senior grounding at 1899 Hoffenheim, where the 2015-16 season brought one league goal in 18 appearances – modest output, but enough to mark him as a useful, mobile full-back rather than just another development-project defender.
His January 2019 move to Celtic from Borussia Dortmund was a short loan spell rather than the main story of his career. It came at a stage when he needed football after Dortmund, and it gave him a taste of Glasgow without becoming a lasting Celtic chapter.
Sassuolo has been the club that gave his career its clearest shape. Across six seasons there, Toljan has made 165 league appearances and scored one league goal, wearing squad number 2 and becoming a regular part of their defensive set-up. His current market value is around £2m, according to Transfermarkt.
Toljan’s career is best read as one that moved through useful early spells at Hoffenheim, Dortmund and Celtic before finding stability in Italy. The Celtic connection is there, but Sassuolo is where the bulk of the work has been done.
