Jurgen Klopp has criticised both BT Sport and the Premier League for a fixture schedule he believes is harming Liverpool's quadruple hopes.
And the Reds boss believes the reason a team has never won all four trophies in a season before is because of the difficulties of adjusting to the fixture timetable at the business end of the season.
Liverpool entertain Benfica in the second leg of their Champions League quarter-final at Anfield on Wednesday night before an FA Cup semi-final showdown with title rivals Manchester City on Saturday afternoon at Wembley.
