City defender John Stones said the players had decided among themselves that Mahrez would take the kick after impressing with his spot-kicks in training last week.
Of course, I did not expect to be saying that after only eight games.
'We showed that we are not just a team that likes to play and leaves big spaces - we are also a team that wants to be strong defensively, and that's what we showed at Anfield'.
"It was a decision I made and hopefully it will be the last time I make that decision at that time". City survived the helter skelter opening ten minutes and after that they dealt with Liverpool's threat well.
"It was a penalty and it shouldn't have happened, but I'm very happy we didn't concede".
Hazard was once again at his imperious best to net his seventh league goal and remain this season's top scorer.
Saints exposed them at the back but missed two sitters, firstly through Danny Ings to go 1-0 up and then when Ryan Bertrand could have equalised.
Pep Guardiola confirms shock team news ahead of Liverpool clash
Against Guardiola, Klopp tends to demand a faster, more direct approach to try to exploit City's high defensive line. I suspect he won't change and will hope Klopp's side are exhausted from the midweek trip to Napoli .
With Chelsea making up ground by winning 3-0 at Southampton, the league's three unbeaten teams go into the global break locked together on 20 points.
Liverpool are now level on 20 points with Manchester City and Chelsea at the top of the Premier League after eight games.
Both managers approached the game as if it was an important one in the title race.
Unlike the four meetings between the clubs in 2017-18, the 0-0 against City was an encounter with little in the way of genuine goalscoring opportunity.
Sadio Mane has scored one goal in his last eight appearances for the club, while Roberto Firmino hasn't scored in his last five matches.
While talking with Sky Sports, he said "If Liverpool are in a really good position in January, I think they've got to be looking to address that [midfield area]", and added "It's not even necessarily having someone who comes in and plays every single game".
Yes it made for a drab game this time, but their real battle is only just beginning.
Everyone misses penalties, even big, big players. When I see one player take the ball and dribble past three, four or five players and score the goal, it depends on him.
