It was only three months ago when Manchester City last played Chelsea - and Pep Guardiola's unbeaten side were stunned twice to go down 2-0 at Stamford Bridge - their first Premier League defeat of the season.
City dominated the match but were hit by a double sucker punch from N'Golo Kante and David Luiz - and slipped behind Liverpool for the first time on the table.
Little did we know that the Reds would get as much as seven points clear before City recently clawed their way back and finally surpassed their title rivals on the standings - albeit having played a game more.
Now Guardiola's City welcome Chelsea at the Etihad Stadium on Monday morning [AEDT] and will be keen to keep the pressure on Reds, who host Bournemouth a night earlier.
XDCity have lost three of their last five Premier League matches against the Blues and only scored four goals in those matches - an extraordinary statistic considering their usual potency in front of goal.
When asked by journalists on how to beat the champions, Sarri revealed the secret on how to set up - but also admitted his team were lucky win the previous fixture against City.
“We need to be very fast when we're recovering the ball. They are able to press really well and it's difficult to find a way out of that situation.
“If we can do that, we can do well.
"I think we were lucky because we scored in a very difficult moment in the match."
Can the Blues exploit City's leaky defence or will the home side continue their revival?
