Mahrez is City’s first signing of the summer and has signed a five-year deal.
The 27-year-old participated in basic training drills along with the rest of the squad and showed plenty of flicks and tricks.
The 27-year-old Algeria winger joined Premier League champions City on Tuesday for what was described as a “club-record” fee reported to be in the region of £60million.
“To all Leicester fans, we have made some amazing memories and history together,” Mahrez said on his personal Twitter account.
“Winning the Premiership (in 2015/16) against all odds was just something else and none of this would have been possible without your extraordinary support for me and the team.
“I want to thank all of you for welcoming me to the club right from the start and continuing to give me the belief and encouragement to achieve what we have together.

“I would also like to thank my teammates, staff and everyone at the club who have become a big part of my life in the last few years.”
Mahrez was wanted by City boss Pep Guardiola in January when Leicester rejected their £50m offer plus winger Patrick Roberts, who was valued at £15m.
“Now it’s time for me to move on and try to build on what I have developed here, but I will always remember my time at the club with great joy and pride,” Mahrez added.
“Thank you, Thank you, Thank you.”
Mahrez – who missed two Leicester games after his proposed January transfer collapsed – was given extra time off by the Foxes after playing in Algeria’s international games in June.
He had been set to return to pre-season training before confirmation the protracted transfer had finally been concluded.
To all Leicester fans,
We have made some amazing memories and history together. Winning the premiership against all odds was just something else and none of this would have been possible without your extraordinary support for me and the team. I want to thank all of you

The Switzerland international, currently on holiday after appearing at the World Cup, has a release clause in the region of £13.5million in his contract and the Potters are resigned to losing one of their most prized assets after suffering relegation from the Premier League.
Shaqiri is seen as a player who will strengthen a Liverpool squad by providing quality back-up to an established front three of Mohamed Salah, Roberto Fimino and Sadio Mane, and it is understood Liverpool have opened talks with Stoke with a view to taking him to Anfield.
Speaking about his future earlier this month, Shaqiri expressed his desire to remain in the Premier League saying: “Of course, I would like to play on the biggest stage in football. Everybody knows that.”
It is believed Stoke are interested in taking one of Liverpool’s youngsters, such as Harry Wilson or Sheyi Ojo, on loan and they hope doing a deal for Shaqiri may help get that over the line.
Ojo, who spent last year helping Fulham win promotion to the Premier League, scoring four goals in 22 appearances despite being sidelined for a time by a dislocated shoulder, has impressed already in pre-season.
The 21-year-old scored in Tuesday’s 3-2 win over Tranmere and is keen to make an impression on boss Jurgen Klopp.
“From as soon as I finished my loan spell at Fulham – obviously, it was a good loan spell – I was just focused on coming back and trying to be as sharp as I can so I can impress the manager,” he told liverpoolfc.com.
“I’m feeling really fit and really positive and the games are going well so far, so I’m excited for what’s to come.
“Personally, I haven’t spoke to the manager yet but it’s been positive feedback in training so far and I’m just really looking forward to the rest of the pre-season. Hopefully I can keep impressing.”
Klopp has a track record for giving young players an opportunity and admits he would be foolish not to give them a chance to break into his squad.
“They have all the quality, you can see that,” he said after the friendly at Prenton Park.
“The boys, we need them. We play the games, we have the training sessions, and then let’s see how it fits at the end.
“But it’s all about the boys, my door is wide open so why should I make a decision today?
“I watch the games, I lead the sessions and then I make a decision at a specific point, but that’s not today and it’s not next week so we have still time.
“I would be really crazy if I would not give these boys a chance – they are fantastic players, they’ve played fantastic games, so we will see what happens.”
