Chasing down a 50-50 ball with the Manchester City goalkeeper Ederson rushing towards him, Mane lifted his book and left it there, resulting in a unsafe collision that could've left his opponent seriously injured.
In contrast, Liverpool goalkeeper Simon Mignolet saw the action from the other end of the pitch and he was keen to stress Mane was going for the ball, not the man. It is so important for us to feel that for our central defenders, with long balls, we have one guy to help us.
Fellow keeper Mignolet said: "I've had it before when you have to jump into people's feet - and you have to be fearless".
City were leading 1-0 when the incident happened as Ederson and Mane contested a bouncing ball. "Unfortunately he is injured but hopefully he will come back as soon as possible".
The former Chelsea and Wolfsburg player has played a vital role in City's attack as Guardiola aims to clinch the EPL cup this season after spending over 500 Million Euros in the summer transfer window.
"Obviously we want to do well in four, so it is very hard to do it in the four". The Blues thrashed the Reds after they went down to 10 men, and we learned many things throughout the match that give us plenty of encouragement for the rest of City's season.
Jurgen Klopp blames Liverpool midfield for Man City defeat
"I wouldn't have wanted to play for a reason like this, an injury to a team-mate, but you always have to be prepared".
Midfielder Georginio Wijnaldum admitted the visitors did not respond well after the red card.
Speaking to reporters after the game, Klopp described Mane's red card as "very unlucky", and said that the winger was "very, very, very upset".
That was the heaviest ever defeat for Jürgen Klopp as a manager and also the first time since 1958 that Liverpool had been beaten by such a scoreline.
"A very unlucky situation".
"I really expect from us that we are much stronger in the first half hour".More news: China eyes ban on gas-powered cars
