Brendan Rodgers watched his new Leicester team return to winning ways on Tuesday night after being appointed by the club on a £5.5million-a-year deal until 2022 earlier in the day.
The move brings an abrupt end to a trophy-laden two-and-half-years at Celtic for the Northern Irishman, who is returning for a third stint in the Premier League.
The former Liverpool manager waved for the crowd and shook hands with those around him as he watched his new side beat Brighton 2-1 at the King Power Stadium.

Rodgers, who was greeted with applause at the King Power Stadium on Tuesday night, said: 'I'm very privileged and honoured to be here as Leicester City manager and I'll give my life to make the supporters proud of their club.
'Together, we'll be stronger and I'm looking forward to working with the players, staff and supporters to make the right steps forward.'
Demarai Gray put Leicester ahead early on and Jamie Vardy added a second, meaning Davy Propper's strike was only a consolation for the visitors.
After the match, England defender Harry Maguire said Leicester's players are excited to get started with Rodgers and believe his appointment is a statement of intent by the club.
'It's an exciting time for the club, I'm excited to get started,' said Maguire. 'We all know his profile and what he's done. We're all looking forward to working with him.
'Celtic are a massive club so it shows how big Leicester are getting and our ambitions. We know he's coached a lot of young players and we hope he can bring them on - we're all excited.'

Meanwhile, Leicester caretaker boss Mike Stowell believes incoming manager Rodgers will bring 'something special' to the club.
Stowell said: 'He's just come into the dressing room after the game. He was very positive, bouncing. We're all desperate to start working with him.
'He said before that he was just going to leave it and observe from up there. He said call the subs yourself and just get on with it but he's going to bring something special to the club.'
At Celtic, Rodgers won two straight Premiership titles and leaves the club eight points clear of rivals Rangers at the summit this season.

Leicester sacked Claude Puel on Sunday, less than 24 hours after a disappointing 4-1 defeat at the hands of Crystal Palace.
The Foxes lost four home games in a row and were without a win since New Year's Day prior to Tuesday's victory.
In the latter stages of Puel's reign at the King Power Stadium, the Foxes were dumped out of the FA Cup at the hands of League Two Newport County, before suffering defeats at the hands of Southampton, Wolves and Palace.
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.'
Meanwhile, former Celtic manager Neil Lennon, who left Hibs earlier this season, has replaced Rodgers in a sensational return to the east end of Glasgow.
Lennon was due to fly to Doha on beIN Sports business on Tuesday but has now abandoned that plan to take charge at Celtic until the end of the season. He will be joined by John Kennedy as assistant manager and Damien Duff as first team coach.
Lennon quit the post in May 2014 after winning the first three titles of the club's seven-year run of domination. Coincidentally, his first game back in charge of Celtic is likely to come against Hibernian in the quarter-finals of the Scottish Cup on Saturday.
Rodgers had planned to see out the campaign with Celtic in the aim of winning a treble of trebles but there was always a hope at Leicester he could be persuaded to forgo those ambitions for another crack at the Premier League.
He said his farewells at Celtic's Lennoxtown training ground late on Monday night with a deal agreed at midnight.
Celtic then said in an official statement that they had given Rodgers permission to speak to Leicester: 'Celtic today confirmed that it has been approached by Leicester City to speak to Brendan Rodgers with regards to their current managerial vacancy.
