Leicester City manager Claudio Ranieri signed a new four-year contract with the Premier League champions on Wednesday, tying him to the club until summer 2020.
The Italian led Leicester to their first ever top-flight title last season, having begun as the rank outsiders at 5,000-to-1 odds.
"From the moment I talked to the owners about their vision for Leicester City, I knew it was something I wanted to be part of for a long time," the 64-year-old told Leicester's website.
"The energy that exists at this club, from the owners and the staff, to the players and supporters, is something very special. I am very happy and proud that I will be part of it for years to come," he said. "Last season, that spirit and our hard work helped us to achieve something magical.
"If we can continue to work hard, maintain our passion and continue to fight with all our hearts, I am sure we can continue to be successful together," Ranieri added.
Leicester vice-chairman Aiyawatt Srivaddhanaprabha said Ranieri had already lifted the club to unimaginable heights.
"Twelve months ago, we brought to Leicester City a man whose knowledge and experience, we felt, could lead us into the next phase of our long-term plan.
"What he would go on to help us achieve, in the time we have achieved it, has been beyond anything we could have anticipated," he said.
"Claudio's qualities, both as a man and as a coach, have been very clear since the moment he arrived, qualities that have helped Leicester City to progress on every level," Srivaddhanaprabha added.
"We have strong foundations from which to keep moving our club forward and I'm delighted that Claudio will continue to be part of that journey."
