Gary Neville has called on Chelsea chiefs to stand by Maurizio Sarri and not sack the under-fire Italian.
Having collapsed in their last away game at Bournermouth, falling to a 4-0 defeat, the Blues found themselves four down just 25 minutes in at the Etihad, before eventually falling to a 6-0 reverse.
Chelsea have failed to score in four away games in 2018, and have fallen to sixth in the Premier League.
"If the ownership of the club really do want a higher quality of football then they're going to have to live through the change.
"Now's not the time to go weak on that. Now what we'll see in the next 24 to48 hours whether Chelsea have the belief that they do want to follow through with it.
"If they really want this type of football in the long term they're going to have to maintain a position of the club and live through the pain and change.”
"It's never been what they've done before but it's how intent are they on seeing that style change," added Neville.
"If they're intent on that style of football changing, they're going to have to maintain a manager and not go back to something that's happened before.
"You talk about Roman Abramovich being motivated by Pep Guardiola's style of play, which is 75 to 80 per cent possession. Chelsea have never been like that."
