Jurgen Klopp believes 'outstanding' Manchester United have what it takes to challenge for the Premier League title next season.
German coach Klopp guided Liverpool to their first top-flight title in 30 years last week after an incredible campaign which has seen his side blow away all competition.
Liverpool are on course for a record points tally in Premier League history and will be looking for another emphatic display against Man City on Thursday night.
Pep Guardiola's side have been Liverpool's closest challengers in the league this season and will be keen to regain their trophy but Klopp believes United and Chelsea are both already showing signs of a title bid next year.
"Yes, City will be strong next season, United will be strong next season, Chelsea will be strong next season," Klopp said when asked about City being the main challengers again.
"They all will be strong next season. Out of the three of them, it’s obvious City is just an outstanding team.
"United are in outstanding shape and Chelsea are in really good shape and doing some interesting business.
