N'Golo Kante says a speech from new boss Antonio Conte helped convince him to leave Premier League champions Leicester to join Chelsea.
The 25-year-old completed a £32m move to Stamford Bridge on Saturday after playing a major role in helping the Foxes win their first top-flight title in his only season at the King Power stadium.
Kante, who was part of the France squad which reached the final of Euro 2016, took to Instagram to reveal words from new Blues boss Conte were enough for him to leave the title holders in a post which also paid tribute to the victims of the Nice terror attack.
"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. The club's project and the coach's speech have convinced me to join this new ambitious adventure.
"I am now waiting to see my new club and give everything for a successful summer... And season of course!!"
Kante is the first big-name player to depart Leicester since their unexpected title triumph, with top goalscorer Jamie Vardy turning down the chance to join Arsenal and instead signing a new deal with Claudio Ranieri's side.
He became an instant hit with the fans and was quick to thank them for their support during what turned out to be an unforgettable year for the former Caen midfielder - who also made his international debut while at Leicester.
"The 2015/2016 past season will remain as an important season for me," he wrote. "After a fantastic season, it ended with a final of Euro 2016. We lost, but we can be proud. The fervour of the French people have given us strength and I wanted to say THANK YOU ALL.
"Of course it has to be appreciated according to the attack that struck in Nice in July 14th and I have at this point a sincere thought for all the victims and their families.
"This season, I also discovered the Premier League with @lcfc. I want to thank the leaders, my team-mates and Claudio Ranieri for this fantastic season that saw us winning the title of England.
"Their confidence and also the fans will forever remain in my memory. And I again thank you all."
Kante is Chelsea's second piece of major transfer business following the acquisition of Belgium striker Michy Batshuayi from Marseille.
