Felix Magath declared himself "disappointed and surprised" to have been replaced as Fulham manager on Thursday, insisting he had been "sure" he would turn things around.
A statement on the club's official website confirmed chairman Shahid Khan had acted following the Cottagers' dismal start to the campaign, with under-21 coach Kit Symons taking up the reins on a caretaker basis.
Magath, speaking in a statement via German news agency DPA, said: "I am disappointed and surprised, because I am sure that I would have stopped the downfall of the club with drastic changes in the squad to a young team, although the first results of the season have not shown this."
Cardiff City manager Ole Gunnar Solskjaer has left the club by mutual consent after nine months in charge, following their disappointing start to the season.
The Norwegian's departure after only eight and a half months at Cardiff was announced in a club statement on Thursday afternoon following talks in London on Wednesday between Solskjaer and the Bluebirds' hierarchy.
The two parties said they parted on amicable terms but Solskjaer made clear it was him who decided to step aside after Tuesday night's 1-0 home defeat to Middlesbrough had seen them fall to 17th place in the Championship.
"I want to thank Vincent for giving me the opportunity to manage Cardiff City FC," Solskjaer said in a statement on the club website
"He has my full respect and I really wish him all the best in his pursuit of making this football club successful.
"However, our difference in philosophy on how to manage the club made me decide to step aside and allow the club to move forward in the direction Vincent wants."
