Towards the end of a first half that had long since become an ordeal for his Manchester City, careering towards a bludgeoning 3-0 Champions League quarter-final loss at the hands of Klopp's coruscating Liverpool, Guardiola might have been tempted to simply close his eyes altogether.
Pep Guardiola's team have looked near unbeatable for much of this season's Premier League, but they've now visited Anfield twice this season and have twice fallen helpless to Liverpool's "heavy metal" soccer.
Liverpool's Egyptian worldwide then set-up Sadio Mane to head home a third goal as the Reds put one foot in the semi-finals of the Champions League with an impressive victory over the Premier League champions-elect.
His performances this term caught the attention of Real Madrid chiefs who are ready to try the possibility of luring him to Spain this summer.
Guardiola, who saw his side defeated 3-0 on the night, said he had not expected to see such behaviour from supporters of a club as "prestigious" as Liverpool.
Liverpool were unable to get back into their first-half rhythm and they suffered a blow when Salah went off injured in the 52nd minute. "We come here to play football, it is sport, and I don't understand this kind of situation", added Guardiola. "I am not angry, it is all good".
"I didn't expect that", he said after the game.
"It was crucial. It was a massive clean sheet for us, not to concede in the Champions League", said Lovren, one of only two fit centre-backs manager Jurgen Klopp has at his disposal. Except 10-15 minutes in the first half when we lost a bit of control. from my point of view, we did really well. Thanks to the lads I mentioned, I wasn't left one-on-one too often and I always had cover around me. Henry claimed "I still don't know what he's good at, ' when he departed the Emirates while Gary Neville said he'd 'snap your hand off" for the money the Gunners were offered.
However, what Klopp appears to be missing is that while the Reds will have a couple of hours at best less to recover from their efforts beating City last night, they'll also have the same couple of hours more of recovery to prepare for what will be an interesting trip to Manchester on Tuesday.
The Reds were cheered on by a fiery crowd at Anfield last night, which made life hard for the away players during the tie.
They're not short on budget and can attract any name out there in world football, so something needs to be rectified in the new season at Old Trafford.
"We know it is not decided". We were deeper than in other moments of the game but that's what you expect against a team like this.
