Manchester City boss Pep Guardiola has taken a swipe at Chelsea's sack culture.
Guardiola revealed his dismay at the pressure being applied by fans to Maurizio Sarri at Chelsea.
The Catalan, who was long-coveted by Roman Abramovich, insists the backing he received from City's hierarchy was the crucial factor behind his success.
"The situation is a little bit different," he said. "In my first year, never the club doubted me. It was never in the media that I'd be sacked if they lose this game or the other game. It never happened.
"I was surprised that when (Antonio) Conte won the title and they lost one or two games at the beginning of the season, people start to say he was going to be sacked.
"I said: 'Wow, but two or three months ago they won the Premier League.'
"The situation is completely different."
