Go to Liverpool’s training ground at Melwood and the walls are adorned with perceptive and emotive quotes from the club’s history.

Jürgen Klopp might be tempted to add another before his side reconvenes to debrief its latest rousing victory over a top-six rival.

“Fool me once, shame on you. Fool me twice, shame on me.”

It was reassuring to hear Klopp confirm beating Arsenal will not taint his assessment of what is required to ensure the real imposters are those who have failed against relegation threatened sides rather than those regularly excelling in games of this stature.

“If we judge the players after the best game of the season, then we sign a contract for another six seasons,” said Klopp.
