Say what you want about Jurgen Klopp but he simply does not do convention. What other manager would have risked his team’s crown jewel in a game of no consequence?
Liverpool versus Porto was never going to be the club’s biggest collision in March. No. That label was attached to March 10. Old Trafford and the shootout, most likely, to determine which Reds at either ends of the M62 will finish best of the rest.
Here was an opportunity, then, for Klopp to give Mohamed Salah the night off and a chance to rest his legs; get him cherry ripe to run at Manchester United’s defence, never mind running at a Porto team that was resigned to elimination from the Champions League.

All seemed to be going to plan. Salah was the on bench and for 74 minutes, he had been a spectator. But then, from nowhere, Klopp turned to his right and invited his No 11 into the action. It was a decision gleefully received by the crowd but it was clearly a gamble.
Fortunately for Klopp, in a game of little drama, Salah never saw too much of the ball and all attentions can now be turned to the High Noon meeting in Manchester. Saying that, attentions had been there for most of the night.
The teams were much changed from the first meeting and the standout selection from the visitors was their decision to give Iker Casillas what, potentially, could be the final appearance in the Champions League of what has been a remarkable career decorated with 21 trophies
Casillas will leave Porto when his contract expires in the summer and, given that he will be 37 in May, it remains to be seen whether another elite club will offer an opportunity. If this was to be the end, then, he wanted one final clean sheet.
What he didn’t want was an experience similar to the one when he first played here in March 2009. Casillas played well that night but he couldn’t stop a Liverpool tornado obliterating Real Madrid 4-0. After what happened in Oporto three weeks ago, many would have envisaged a similar score here.
A 5-0 advantage from the first meeting, however, meant this could not be the kind of game you associate with Anfield on European night, when the stadium hums with noise and expectation. It was a box-ticking exercise, the tie having been decided in a torrent of goals in Portugal.

You could tell that by looking at Klopp. His programme notes anticipated that Liverpool, the Champions League’s highest scorers so far, would attack when he wrote: ‘they cannot ease off the accelerator even for one second.’
There was no windmill-like waving of his arms; no screeching, no sign of the piercing dog-whistle that he deploys when he wants his team to get back into position. He has been more animated in pre-season contests than he was on the touchline here.
It ensured the opening half was resembled the opening exchanges of boxing match when neither fighter wants to get hurt, as both sides danced around, bobbing and weaving, but never threatening to throw a meaningful blow.
Belated, Liverpool began to find some rhythm and purpose. The first proper sight of goal arrived in the 17th minute, when Joe Gomez scampered down the right and his cross, while too high for Roberto Firmino, was met by Sadio Mane but his acrobatic effort whizzed over the bar.
You anticipated that Liverpool would step up a gear and begin to hem Porto in but the anticipation was misplaced. Liverpool would only threaten twice more before the interval, Mane striking the base of the post with a thumping drive and Dejan Lovren heading over from six yards.
Come half-time, the thoughts of many within the stadium had begun to drift to Old Trafford on Saturday with the main question being: how long would Firmino and Mane be allowed to continue when there was a chance to give them rest?

Klopp, though, was in no hurry to give them a breather despite the match ambling towards its inevitable conclusion. Firmino, too, was in no hurry to come off, given he is one goal away from equalling the club record for most goals (nine) scored by one player in a European campaign.
There was one chance to draw alongside Dean Saunders, whose haul came in the 1991-92 UEFA Cup, but Firmino’s attempt was blocked in the 59th minute by the outstretched leg of Porto captain Felipe after Jordan Henderson ushered him forward.
Klopp decided at that point enough was enough and ended Firmino’s evening. Henderson, for differing reasons, could also have made an early exit for a heavy tackle on Jesus Corona but referee Felix Zwayer showed a yellow card. A more impetus official may have deemed otherwise.
From that point, it became clear there would not be a goal. Substitute Danny Ings did his best but Casillas stood firm and earned his ovation at the end. For Liverpool bigger tests – starting Saturday – await.
