Chelsea boss Maurizio Sarri and Manchester City boss Pep Guardiola met for dinner in June, a month before the Italian was confirmed as Chelsea’s manager.
Ahead of Saturday’s game between Chelsea and Manchester City at Stamford Bridge, Sarri has revealed Guardiola warned him his first Premier League season might not go according to plan.
“You need a season just to understand the real situation here,” Sarri added.
“He told me the first season in England is really very difficult. It’s impossible to improve 20 players in the first season.
“He told me, in the first season, you have to work only on 14 players otherwise you are in trouble. You need too much time to improve all the squad.”
Guardiola spent around £200 million in the summer of 2017 to turn Manchester City into champions but Sarri insists he won’t spend freely like Guardiola to turn Chelsea into champions.
“You cannot think that you can buy 11 players without problems,” Sarri said.
“If you do, the problems will be the same. You have to create a new mentality and a new style of playing.
“We need to improve. We need to arrive at 95 per cent of our potential. And then we can get the last five per cent with a new player. With a new player, not 11 new players.”
