Former Italian coach Claudio Renieri will return to the English Premier League, which will lead Lester to a historic title in 2016, after Fulham appointed him as coach on Wednesday and fired Slavica and Kannowitz.
Fulham has a disappointing season, with one win in 12 games, and the last 6 games losing five points.
"Shahid Khan (owner of the club) today announced the appointment of Claudio Renieri as Fulham's football coach instead of Slavica Gannovic," he said on his official website. "He returned to the Premier League in May 2018.
Ranieri, 67, is one of the most experienced coaches in the world. He oversaw several clubs like Naples, Fiorentina, Parma, Juventus, Roma, Inter Milan, Valencia, Atletico Madrid and Spain.
Ranieri was without work after being dismissed from the Italian training of Nantes before the end of last season.
"I am honored to accept Mr. Khan's invitation and the opportunity to lead Fulham, the wonderful club with tradition and history," Renieri told the club's website.
"The goal at Fulham is not only to remain in the premiership, we have to be tough opponents and we expect success."
In turn, he thanked Khan Jocanovic, 50, who became the first coach to be named this season in the English Premier League.
The appointment of Ranieri comes weeks after the departure of his former owner Licester Vichai Srivadanabraba in a helicopter crash near Leicester Stadium.
Ranieri is on his first game as coach of Fulham 10 days later when he meets South Hampton 17 at Crippen Cottage, and then turns to Chelsea and Leicester.
