Sarri, while beaten by Guardiola's Manchester City in the Community Shield, admits the Catalan was the biggest influence on his decision to join Chelsea. The worry for the rest of the Premier League is they have the appetite for more.
Manchester City's Argentinian striker Sergio Aguero (3rd L) shoots to score their second goal during the English FA Community Shield football match between Chelsea and Manchester City at Wembley Stadium in north London on August 5, 2018.
Another huge factor was the contribution of Aguero, who passed 200 goals for the club with a brace.
Asked about the performance of Stones against Chelsea and his options at the back this season, Guardiola said: "John made an excellent World Cup and showed again his personality".
"I want the best players to stay, obviously, but the club will decide and then we will see what happens at the start of the season".

"We were not in control of the match". Both goalkeeper Thibaut Courtois and midfielder Eden Hazard are still on their breaks after helping Belgium to finish third at the World Cup.
"We would like to find maybe one more because we do not have two specific players to substitute Fernandinho. It's not very easy".
"I think it's good news for us for the season".
