Referee Jon Moss brandished the red card to the Liverpool forward, with Ederson taken off on a stretcher and replaced by Claudio Bravo. "The goalie came more in his (Mane's) direction". Ritchie should have gone, too.
Jamie Carragher believes Jurgen Klopp was at fault for rotating his back four ahead of Saturday's miserable 5-0 loss away to Man City. However, before the incident, Guardiola had set up his team to strangle the match and his side were in control.
After their 4-0 knocking of Toolbox, Liverpool began vibrantly with Mohamed Salah creating Nicolas Otamendi plenty of troubles in the opening phases.
A number of City's players caught the eye but link-up play between strikers Aguero and Jesus was highly encouraging for boss Pep Guardiola.
"The problems come at the back and were brutally exposed in the second half in a terrible display, even given for the fact they were down to 10 men".
Liverpool were ripped apart by Manchester City at the Etihad Stadium yesterday and the fans are rightly furious.
Instead, City got such a fulfilling win from a relatively unfulfilling game.
Klopp then made his second questionable selection decision of the game after first playing the Estonian centre-half by withdrawing Salah for Alex Oxlade-Chamberlain, as the new signing was subjected to his second successive Premier League thrashing - albeit for different clubs. He allowed the more creative players to expose the weaknesses shown by Ragnar Klavan, Joel Matip and the inexperienced Trent Alexander-Arnold by controlling the game, breaking up play and moving the ball intelligently and quickly. Benjamin Mendy, Kyle Walker, Danilo... they have a lot of legs! He makes a huge amount of passes, he is quick and he always sees spaces where others do not.
The Reds had started brightly but found themselves 1-0 down when Sergio Aguero opened the scoring and then a man down after Mane was given his marching orders having collided with Ederson trying to get on the end of a through ball.
Mane, 25, who has never won the award before, has been recognised after netting three goals in three games for Liverpool - making him the Premier League's joint-top scorer this season alongside Romelu Lukaku.
