The former Nottingham Forest boss has signed a three-year contract with the Foxes.
He wrote this morning: "I am very proud to be joining a club with a rich history, and I want first of all to thank Khun Top for the opportunity to manage Leicester City. I recognise I am joining a group of people who love this Club and want the very best for it.
"I congratulate the players and staff on the achievements of their promotion to the Premier League. I know how hard that is. Any person who loves football can only look with great respect upon how much this Club has achieved in recent years. The Premier League title of 2016 and the FA Cup of 2021 have demonstrated what’s possible for a united club. As the new manager, I don’t take that legacy lightly. My job will be to build on those achievements and to bring everyone along – players, staff and fans. Great challenges lie ahead but I get the feeling that Leicester thrives in these moments. I know we will be ready.
"The work starts now on building towards a successful Premier League season. Our aim is to once again make Leicester City an established Premier League club, and one that can look forward to the future with pride and ambition. To do that we have to show to our fans that we are ready to adapt to the new level after a season in the Championship. I know that my experience will be valuable in helping that evolution, with an excellent group of players working from one of the best training grounds in the world.
"As staff and players, it is important we play with a style that the Leicester support recognise as the very best of their Club. The support of the fans will be fundamental and I am looking forward to meeting many of you over the summer.
"This Club has a distinct identity and attracts a great deal of respect for what it has achieved. That has been done through the dedication of the owners and the hard work of the players and the people here.
"I take the faith the Club have placed in me very seriously and am committed to immersing myself in what the Club and community stands for and ensuring we have success together.
