The 55-year-old was shockingly sacked by Bayer Leverkusen just two games into their 2025-26 Bundesliga campaign, in which they lost 2-1 to Hoffenheim and drew 3-3 with Werder Bremen.
Ten Hag was chosen to replace club legend Xabi Alonso, who departed for Real Madrid at the end of last season.
The former Man United manager has since released a statement regarding his dismissal, hitting out at the German club over his treatment.
He said: "The decision by Bayer Leverkusen this morning to put me on a leave of absence came as a complete surprise. To part ways with a manager after just two league matches is unprecedented.
“This summer, many key players who were part of past successes left the squad. Building a new, cohesive team is a careful process that requires both time and trust.
“A new coach deserves the space to implement his vision, set the standards, shape the squad and leave his mark on the style of play.
“I started this job with full conviction and energy, but unfortunately the management was not willing to grant me the time and trust I needed, which I deeply regret.
“I feel this was never a relationship based on mutual trust.
“Throughout my career, every season I have been able to see through to the end as a coach has brought success. Clubs that placed their trust in me have been rewarded with success and silverware.
“Finally, I would like to thank the Bayer Leverkusen supporters for their warmth and passion, and I wish the squad and staff every success for the remainder of the season."
