In truth, Jurgen Klopp’s side was handed the victory on a plate after Chelsea defender Andreas Christensen was shown a red card for hauling Mane to the ground, before yet another error from under fire goalkeeper Kepa Arrizabalaga gifted the Senegal international his second.
Liverpool still looked vulnerable even against 10 men and had goalkeeper Alisson to thank for keeping the score at 2-0, after the Brazilian saved Jorginho’s penalty in the second half.
There was also a debut for Liverpool new boy Thiago Alcantara, signed from Champions League winner Bayern Munich last week, who was introduced at half-time to replace Jordan Henderson.
It was an accomplished Premier League debut from the Spaniard who, despite only playing 45 minutes, completed more passes than any Chelsea player.
“He was top,” Klopp told reporters after the match. “Top timing, I would say. He is not used to our thinking yet and Bayern played differently to us. Defensively it was tricky for him but with the ball, he wants to pass it.
“I think it helps, of course, that it was the perfect step in [against 10 men]. We scored two goals when he was on the pitch and he played a good game. Everybody could see what he is naturally doing, because we didn’t speak to him about anything we wanted, he just played it.
“It’s clear when you understand — he wants to switch, he wants to chip, he wants to do these things so we let him do it and he did well.”
Elsewhere, Liverpool’s city rival Everton maintained its 100% start to the season, with summer signing James Rodriguez grabbing his first goal for his new club. Arsenal, Leicester City and Crystal Palace are the only other teams to have won both matches since the start the season.
