Both teams are now locked on 19 points after seven games, and it's a hard match to call, despite Jurgen Klopp's impeccable record against Pep Guardiola at Anfield. Like Guardiola, Emery was also 100% in September with Arsenal and may provide the toughest competition for the prize.
Sources said that the Florida-based Glazer family do not want to terminate Mourinho's contract, which is due to run until June 2020, despite the recent run of form that has seen them slump to a mid-table position in the Premier League and suffer Carabao Cup elimination at the hands of Championship outfit Derby County.
City defender Walker is hoping he and his team-mates can make a statement in the match, but acknowledges that Jurgen Klopp's side are serious challengers.
"I didn't want to lose at Napoli but, if you ask me which is the best preparation mood wise, it's losing a game".
"I grew up in a time when Boris Becker and Michael Stich were the best tennis players in Germany and maybe for a few years in the world", Klopp explains.
"The problem (against Liverpool) in Premier League (last season) is that we conceded three goals in five or six minutes and we have to avoid doing that". I'll therefore go for Over 3.5 Goals at [2.6]. Against Guardiola, Klopp tends to demand a faster, more direct approach to try to exploit City's high defensive line.
Of course, that 1-0 loss was only Liverpool's second of the season, and neither of those reverses have come in the Premier League. After none of these games you go into the dressing room and think, "Now we know how to beat Manchester City", because there is no real way, no one thing that you have to do.
Guardiola has lost both of his Premier League games at Anfield, and Opta tell us he has never lost three straight league matches away to the same opposition.
Midfielder Naby Keita is struggling to be fit after a back spasm, so skipper Jordan Henderson could return to the starting XI.
If Liverpool need to restore any confidence, they need only look back at their last three games against City -all wins.
