''Aside from a short spell out on loan, Adam was a TSG player for five years in total - that's unquestionably a long time in today's fast-moving football world. Adam scored some very important goals during his time here at the club. One that springs to mind was on the last day of the 2017/18 season, when he scored in a 3-1 victory over Borussia Dortmund and in doing so helped secure the club's first-ever qualification for the Champions League,'' says Alexander Rosen, Director of Football at TSG, going on to add: ''Discussions with the player started towards the end of last season and now we wish him all the best for the future, both in his personal life and his footballing career.'' Rosen made sure to expressly thank the striker for his exceptional commitment and high level of performance throughout his time at the club.
The return to Mainz means that things have gone full circle for the 31-year-old centre-forward, as it was here that Szalai was first able to establish himself as a Bundesliga player. In his previous spell in Mainz, the Hungarian formed part of a formidable offensive trio alongside André Schürrle and Lewis Holtby. A transfer to Schalke followed, and then, in 2014, Szalai moved to Hoffenheim, where he - with the exception of a six-month spell out on loan at Hannover 96 (2016) - would go on to play in 113 competitive matches and score 25 goals. The Hungary international's contract with the club was set to expire in the summer of 2020.
