Manchester United manager Jose Mourinho has reportedly been left angered by the easy nature of Liverpool's schedule for the 2018-19 Premier League season.
According to The Times, Mourinho has privately questioned why the Reds have been handed six home games in the weekend slots that immediately follow Champions League matches.
By comparison, the Red Devils, Tottenham Hotspur and Manchester City have a mix of three home and three away games after competing on the continent.
United have been handed a favourable start to the new season, as they face just one of last season's top six - Tottenham - in their opening eight matches.
Mourinho, whose side face Leicester City at home in their opener, complained about United's fixtures at the start of last season.
