Manchester City striker Gabriel Jesus has signed a contract extension that will keep him at the club until 2023. He cites their half-time formation change against Arsenal back in 2016 - the switch that ultimately led to the Premier League title - as an example of their tactical flexibility.
The two men were brought together in June by Arrigo Sacchi, the former AC Milan manager, and while Guardiola urged the former Napoli manager to move to the Premier League, he recalled his own problems in his first year at the Etihad Stadium before overseeing last season's stroll to become champions.
Despite that disappointment he is again set to challenge Sergio Aguero for a starting berth in the City line-up as they pursue more silverware following their league and Carabao Cup success in 2017-18.
Chelsea take on Manchester City in the Community Shield on Sunday before kicking off their domestic campaign on Saturday, August 11 at Huddersfield Town. "He had some problems in the first season, but he said that football is football everywhere".
"I don't have an answer, I'll try to do what I did in Barca and Bayern, to be harder with my players".
With a knowing smile, he spoke of being Chelsea manager for "10 years". When asked if Willian would remain at Stamford Bridge, Sarri told Sky Sports: "Yes. I am very lucky to be here". "We can not deny there are more contenders - Chelsea, United, Tottenham, they have excellent players and that's why no team has back to back in 10 years".
"Yes, we were close but in the end Jorginho made a decision to stay with Sarri", he said.
"Also thanks to the Club for being so organised and focused since I arrived". 'It is hard because Manchester City have been working together for two years. "There is not a problem with Willian". "Congratulations to him [for his new contract] and thanks to him for his trust to stay with us for longer". "Every game shows you if you are on a good path".
