"At the beginning of the new season, I chose to join @chelseafc", he wrote.
"It is a great club, which has just recruited a great coach and want to reach high ambitions I share".
Leicester will ask more than 30 million pound ($39.5 million) to let one of their most shining star leave the club and Chelsea seem to be eager to meet both the club and the playerâ€™s request. The club's project and the coach's speech have convinced me to join this new ambitious adventure. "And season of course!"
Leicester secured an unforgettable title triumph last time around but their fairytale was hit with a harsh dose of reality over the weekend when influential midfielder N'Golo Kante completed a big-money move to Chelsea.
Reports that Riyad Mahrez has turned down Leicester City's offer of a new contract are believed to be wide of the mark.
Kante cost Leicester a reported £5.6m fee when they signed him from Caen past year.
Arsenal triggered Vardy's £20million release clause, but the 29-year-old made a decision to reject their offer in favour of remaining with the Premier League champions.
Ranieri says it is even more unlikely that they will emerge on top in 2016-17 and is therefore setting safety as the No. 1 objective, although he is not ruling out delivering more success for the Foxes while keeping a low profile. We lost, but we can be proud.
"Their confidence and also the fan's will forever remain in my memory".
"Finish in the top 10; [qualify for] the Europa League; a place in the Champions League".
