Leicester City have confirmed the appointment of Brendan Rodgers as their new manager until June 2022.
The Northern Irishman is back in the Premier League after almost three years at Celtic, where he won seven trophies and has the club on track for a third successive domestic treble.
Leicester moved quickly for Rodgers after sacking Claude Puel following the 4-1 home defeat to Crystal Palace.
Sky Sports News understands Rodgers informed Celtic's players on Monday afternoon that he was leaving, having also told the board of his desire to join Leicester.
Rodgers' first game in charge will be Sunday's game against his former club Watford, live on Sky Sports Premier League.
Chris Davies will be Rodgers' assistant manager at the King Power Stadium, with Kolo Toure a first-team coach.
"I know I'm joining a fantastic club that has grown so quickly over these last few years," Rodgers told LCFC TV.
"I'm just delighted to be here. I think there was a number of reasons [why I joined]. I was certainly in no hurry to leave Celtic.
"Celtic is a club that's a huge club worldwide, a renowned club, and I loved working with the players there.

"We were on a journey of great success over these last years but when the opportunity came to talk to Leicester and I was able to analyse it, it allowed me to think that I'd probably achieved and taken the club maybe at Celtic as far as I could at this moment.
"The opportunity to speak with Leicester and find out their ambitions and where we can grow the club and the training facility. Of course, the big attraction for me is working with the players.
"It's a young squad, a very dynamic squad, it's got huge potential and you've got some of the players with good experience also. There was a number of factors in being here and, like I say, I'm absolutely delighted."
Rodgers previously managed Swansea City and Liverpool in the Premier League and becomes the Foxes' third permanent manager since they axed their title-winning boss Claudio Ranieri in February 2017.
Leicester sat 12th in the Premier League ahead of Tuesday's home game against Brighton, eight points above the relegation zone.
Leicester City Vice Chairman, Aiyawatt Srivaddhanaprabha, said: "I'm absolutely delighted to bring a manager of Brendan's calibre to Leicester City and I look forward to seeing what he, our talented, young squad and our dedicated, skilled team of staff can achieve together.
"As projects, including the development of our new training ground and the proposed expansion of King Power Stadium continue to take shape, and as a young squad of great potential begins to mature, Brendan and his colleagues arrive at an exciting time for Leicester City.
"We're continuing to grow as a club and I am anticipating that Brendan's coaching methods, knowledge and experience can enhance our journey."
