The day after Liverpool had thrashed Crystal Palace and the squad had gathered at Melwood to go through a routine warm down session.
Jurgen Klopp, not surprisingly, was in high spirits. He had seen his side score four goals, extend their unbeaten run to 11 games with an exhilarating display of attacking football. Liverpool's manager, as is his way, was keen to stress to all involved at Selhurst Park how good they had been as a team.
There was, however, something a bit different about Klopp on this afternoon. It is rare for him to single out players but, given what he had seen in South London the previous evening, he couldn't contain himself.
