Liverpool manager Jurgen Klopp has taken a sly dig at Manchester United's struggles in the Europa League.
Jose Mourinho's side hampered their chances of qualifying for the knockout rounds after losing 2-1 to Fenerbahce in Turkey on Thursday night.
The Red Devils currently sit third in Group A, one point adrift of Fenerbahce and Feyenoord, who sit first and second respectively.
Liverpool are not playing in Europe this season having failed to qualify for either competition, and when asked whether the lack of added fixtures has boosted the club's league campaign, Klopp mentioned that United could be in a similar position soon.
"For the last six, seven years I was always travelling through Europe," Klopp told reporters in Friday's press conference. "I never thought 'this is too much'. If you want to be successful, you need European football.
"We have to show we use the time for training over the whole season, not the first 10 games. Did you ask the same of [Chelsea boss] Antonio Conte? They have the same situation. Maybe Manchester United have the same from January onwards?"
Liverpool are currently third in the Premier League table, eight points above their arch rivals United, who sit eighth.
