THEY could surely have played in red against a team wearing blue and white.
Yet Liverpool’s men in bright orange delivered yet another absolutely dazzling performance away from home in their third kit for Jurgen Klopp.
And this ridiculously-easy win in the last 16 means those who hate English football should look away completely when the draw for the Champions League quarter-finals is made.
There could certainly be a few of our teams involved.
This outstanding five-star, five-goal performance underlined the team’s improvement and Klopp has got the club’s fans dreaming about 2005, all over again.
Despite getting some stick, Sadio Mane delivered a hat-trick against a Portuguese side who had not lost in the League this season but completely buckled when faced with Klopp’s potent attack.
Once again, you had to give credit to Mo Salah, who is proving to be a £34million bargain, if there is such a thing.
His 30th goal of an already outstanding season at the club – how former club Chelsea must be cursing – means he is the second quickest player to reach that landmark for Liverpool.
George Allen was still the fastest off the blocks – back in 1896 – but the fact Salah has reached 30 quicker than the long list of outstanding Liverpool goalscorers shows you how good he has been.
Roberto Firmino made it 4-0 before Mane completed this special evening.
Liverpool put their fans through the wringer in Sevilla in the group stages by tossing away a three-nil lead to end up with a draw but there as no repeat.
It was another free-scoring performance – that is now 99 for the season – but it also included a third successive away clean sheet.
And this famous result, another one in Liverpool’s European history, capped a staggering couple of days for the premier League following Manchester City and Spurs’ results.
So over to you, Chelsea and Manchester United.
On a mild but wet evening in northern Portugal, the atmosphere was as you would expect on this type of game. Firecrackers, flags and a PA announcer who had sounded as though he had been trying some of the local port.
The Porto party soon stopped.
As soon as Liverpool stepped out in that ‘bold citrus’ kit, you knew we would see a bundle of goals.
Liverpool gave it a run out in Slovenia against Maribor and they won 7-0 and then wore it for the 4-1 win at West Ham, 3-0 triumph at Stoke, 3-3 draw at Arsenal and Sunday’s 2-0 victory at Southampton. And it was the same here.
It was a sixth game for Virgil van Dijk and his first in the Champions League since playing for Celtic in a 2-0 defeat at Malmo in August 2015. Although £75m was a silly amount, he has certainly helped this team improve at the back.
Porto went into the game with bangs of confidence but remarkably, never got close to landing a punch on Klopp’s team.
One blow was the absence of star striker Vincent Aboubakar who had scored five Champions league goals including two in the astonishing 5-2 win over Monaco in December.
That result proved beyond doubt what Sergio Conceicao’s side are capable of but here, they could not cope with Liverpool’s dominant midfield and super-fast counter attacks.
After a slow start, Liverpool found their gear, pushed Porto back and started to find space and the opening goal, albeit a scruffy one, was not exactly a surprise.
Gini Wijnaldum’s shot hit an opponent in the face but he kept focus and played the ball out to an unmarked Mane.
His shot was not particularly good and his effort squirmed under the body of keeper Jose Sa.
Legendary Spanish keeper Iker Casillas, who has been relegated to the substitute’s bench, will have watched that howler through gritted teeth.
The second goal was also untidy, not that any of the Liverpool fans stuck up in a corner at the side of the pitch would have cared.
The impressive James Milner won the ball off Moussa Marega with Porto claiming a foul although that would have been harsh.
Milner continued, dropped his shoulder, lost a man and sauntered into the box before seeing his effort hit the post.
Salah reacted first with Alex Telles sleeping. Salah took a couple of touches and then headed the ball towards his left foot before scrambling the ball over the line.
Mane pretty much sealed the tie and their top trio were all involved.
Salah released Firmino his effort was parried by Sa and Mane had an easy effort to score.
Milner then crossed for Firmino for 4-0 and the fifth came when mane slammed the ball into the net.
Michael Owen is the only other Liverpool player to score an away hat-trick in Europe.
Since they last featured in the Champions League, Philippe Coutinho has left for Barcelona but it is a testament to the character of this team – and talent of Salah – that no-one is talking about him.
Klopp will not be taking anything for granted when Porto head to Anfield on March 6 but in truth, they should save themselves the trouble and not bother going to Merseyside.
They should concentrate on winning a Portuguese Cup double.
As for Liverpool, they head off to Marbella today for a four-day training camp as they are not in the FA Cup.
The fourth round defeat to West Brom ended any realistic chances of silverware this season. Or so we thought.
In the pre-match press conference Klopp reacted angrily when asked about the famous 2005 triumph but if Liverpool keep doing this, and destroying teams who batter the likes of Monaco 5-2 at home, the questions and comparisons will continue.
And those fans may start to keep a date in their diary for an evening in Kiev next May.
