Sunday's game between Liverpool and Manchester City was a fairly clean affair.
Referee Chris Kavanagh only blew for 17 fouls - fewer than in any of the other nine Premier League matches over the weekend.
However, the was still a bit of needle between the two teams.
Liverpool fans wound up Pep Guardiola by chanting that the City manager would be 'getting sacked in the morning'.
Guardiola responded by holding up six fingers. Not to point out that City have now lost six of their last seven games, but to signify that he has won six Premier League titles during his time in Manchester.
