"To be honest I was shouting a bit at half-time", said Lovren.
Jurgen Klopp's side, who stunned the Premier League champions-elect with a 3-0 win at a frenzied Anfield, knew an away goal would make City's task tougher still, and after Salah delivered the demoralising punch (56), Firmino added further insult (77) as the hosts ran out of steam.
It was clear Guardiola had a sizeable rebuilding job on his hands, and he may feel in a similar position now if City are to hurdle the latter stages in Europe next year.
Sadio Mane powered his way into the and when he fell under the challenge of Ederson, Salah kept his cool to clip into an empty net. "But Mateu Lahoz is a special guy, he likes to be different, he likes to be special", he said.
Klopp had warned of a brewing City "thunderstorm" after their Manchester derby defeat made them wait for the league title and the perfect start to the perfect game Guardiola called for came when Fernandinho slid through a ball that Raheem Sterling squared for Jesus.
"We need to learn from this and turn the page quickly to focus on Tuesday and the rest of the championship. Whenever people see the things, he will decide the opposite", Guardiola said.
It was evidence of what United are capable of when the gloves are off. At 2-0 down they had to go for it, but all too often Mourinho has been overly cautious with his starting tactics, with Paul Pogba's lack of freedom in midfield a particular point of debate. Perhaps it will have convinced Mourinho to move his star player closer to the attack, with a home game against the basement side providing the perfect opportunity to experiment.
"From a personal point of view I don't want Real Madrid in the semi-finals".
"When you concede one goal and score five against Manchester City I think we should respect Liverpool more". But it is vital that Hodgson's side claim a win this weekend to kickstart their survival bid - and what better fixture to do it in than at home to bitter rivals Brighton. Given all the off-field distractions this season, victory against the Gunners en route to a top-half finish would be a remarkable achievement.
