Manchester City manager Pep Guardiola has defended his Chelsea counterpart Maurizio Sarri.
The Spanish tactician stated that Italian coach Sarri should be given more time following City's commanding 6-0 win over Chelsea in an English Premier League (EPL) match on Sunday night.
It is the Blues' heaviest loss in any competition since 1991 and Sarri's worst league defeat as a professional manager.
"Yes of course. I know exactly what he wants to do. I think this kind of person - it always helps to make our (Premier League) football better," Guardiola said on Sky Sports News.
"They beat us at Stamford Bridge - and against Napoli last season (UEFA Champions League) - they were tight games. During moments of those games, they were better than us.
Sarri replaced his compatriot Antonio Conte as Chelsea manager prior to the start of the current season.
"People don't understand how difficult it is. I said many times, my first year was difficult too. Some moments we played good but not consistently," he continued.
"People expect 'Okay, manager arrives, he buys players and immediately come [results]' - it needs time. It depends on the belief from the owners, the people who are in charge; they really need to believe in that.
"The main reason I decided to come to Manchester City is because my bosses, the chairman specifically, I didn't have to convince him. He knows me."
The defeat left Chelsea placed sixth on the league standings, while City climbed up to the top of the table.
