Eintracht Frankfurt confirmed the appointment on their official website. Hütter managed the club between 2018 and 2021, winning the DFB-Pokal in 2018 and guiding them to the Europa League semi-final in 2019, before departing after three seasons. He subsequently joined Gladbach and then moved on to AS Monaco before the call from Frankfurt came.
Frankfurt sporting director Markus Krösche explained the rationale simply.
"Adi Hütter stands for courageous attacking football, clarity and discipline. He has shown at his previous clubs that he can combine fast transition football with possession play."
Hütter himself was emotional in accepting the role.
"For me it is something very special and emotional to be head coach of Eintracht again. The time we had together in Frankfurt shaped me and I never forgot it. Looking back, I always had the feeling that I was not finished here."
He replaces Dino Toppmöller, who was dismissed in January after a run of poor results with the club sitting in the lower half of the Bundesliga table. Frankfurt ultimately recovered to finish eighth, securing mid-table safety without making any impact in the cup competitions.
Frankfurt's previous Europa League title came in 2022 under Oliver Glasner, who has since moved on to Crystal Palace and won the Conference League. Hütter's first stint pre-dated that achievement, but the ambition he showed in European competition during his original tenure is what the club is looking to recapture.
