Jurgen Klopp and Pep Guardiola put Sunday afternoon's controversial Premier League game to one side after the pair were pictured leaving a UEFA summit on Monday as the Premier League bosses looked to take the fight to football chiefs over fixture congestion.
The Liverpool and Manchester City managers have spoken out against the number of fixtures facing their respective teams in quick succession, while Klopp will field two different sides in the space of 24 hours as the European champions face games in two separate competitions.
And it is believed that the German and Spaniard are using the summit as a platform to air their concerns to football chiefs, in the hope that leniency will be given over the busy footballing schedule facing both sides.
Klopp has been critical of the lack of communication between separate football bodies when planning competitions.
He said: 'I do not want to cancel English cup competitions! But the problems are obvious. We respect the competitions.
'The situation is clear. There would be a few solutions possible, but there was not one day where FIFA, UEFA, the Premier League, the Football League, that they have to sit at a table and think about the players and not about their wallet.'
It's likely to have been a prickly meeting between the Premier League rivals after Sunday's clash at Anfield, in which the league leaders came away with an emphatic 3-1 win over the reigning champions.
