Naby Keita scored his second goal in as many games after five minutes and Roberto Firmino got the second in the 26th minute. Marega kept plugging away to try and find the away goal that would pull Porto back into the tie, but only one of his many second-half efforts forced Alisson into a comfortable save.
Liverpool, meanwhile, will be slightly relieved to come away without conceding any away goals after Moussa Marega squandered two big chances. The first half is played and now we have a bit longer than 15 minutes to prepare for the second half.
The Liverpool manager also offered an apology to Jordan Henderson, who impressed playing in the more advanced role that he prefers. It was pretty much clear, and we scored two wonderful goals.
Mohamed Salah ended his eight-game goal drought as Liverpool returned to the top of the Premier League table with a 3-1 win at Southampton on Friday, but the Egyptian got his angles wrong when he failed to hit the target with just Casillas to beat.
"Were we complacent? Maybe, but that may be natural when you have such a convincing victory and Liverpool have to treat this as a completely new challenge now".
As mentioned, Sergio Aguero makes our Team of the Year, and the Argentine is joined by City team-mate Raheem Sterling, who was the fourth and final player to be chosen by all of us here at Eurosport. Porto must be sick of the sight of Liverpool in the Champions League. 2-0 is a really, really good result.
In the build-up to Liverpool's first goal, Danilo won the ball but because of Liverpool's press, James Milner mopped up the loose ball and played a brilliant first-time pass to Sadio Mane.
The England global set-up Sadio Mane with a perfectly weighted clipped ball in the second half, but the goal was rightly ruled out for offside.
"We wanted to be as good as possible tonight, and 2-0 is a fantastic result, with the clean sheet, what more could we want? When we attacked them, we caused Liverpool lots of problems". Although they couldn't score in the second half, they prevented Liverpool from increasing the 2-0 margin which gives them a good chance to turn the tie around in the second leg.
