Klopp has had to field weekly questions about the title race and how they handle the pressure but now it is about how they react.
Ever since falling behind, Man City have clawed back a large amount of lead in order to get back level with Liverpool but Pep Guardiola feels that the pressure is still on them. "It wasn't a choice, it was a necessity". "We want to play convincing football we want to perform".
The Argentine made an instant impact with his first two goals in just his second Premier League appearance in a 5-0 thrashing of Huddersfield last weekend to right the Chelsea ship after the Bournemouth debacle. The most important line said "Unity is Strength" and I can think of no better message at this time. Sarri says City's patient approach was rewarded, with City's remarkable title success last season built on recruitment and following Guardiola's approach.
Klopp's men will have a game in hand over the champions after they play today and the title is still very much theirs to lose.
"You know very well that the midfield of Manchester City is one of the best in the world". So it's a very hard match.
Guardiola conceded that it could yet be some time before Mendy, who also spent most of last season on the sidelines, returns to full match fitness.More news: Don't dismiss Giants in Bryce Harper sweepstakes
Manchester City have two first-team players unavailable for tomorrow afternoon, which ought to offer Chelsea at least some encouragement. City have played a game more due to bringing forward the game v Everton by two weeks.
Pep Guardiola and Maurizio Sarri share a mutual admiration and style of play, but as Chelsea visit Manchester City on Sunday, Sarri is also following Guardiola's experience of a hard first year in England. "I think we have a good mix and balance and that is going to be useful". "In that match we defender very well as they only had three opportunities on goal, no more".
"Then it was something that City lost to three teams outside the top six, we drew twice". "Because you have experienced it before and you know exactly what can happen".
He added: "The situation is not like the other match, so I can decide something different or have a "false nine".
Instead he has kept a consistent focus on his own team's performances.
Wijnaldum battled illness during the week, but put in a standout goalscoring display on his return to action. I have to decide.
Asked if he still expected to relocate before the end of the season, the Argentinian said: "My gut feeling (is that) it will be tough but I hope and I wish to be in the new stadium playing".
