Liverpool manager Jurgen Klopp says Manchester City are the best team in world football.

The Reds are five points clear of City on the Premier League table after five games.

But Klopp insists his team are still behind Pep Guardiola's reigning champions.

"We cannot be the best team in Europe because Manchester City are the best team in the world - and that is the same planet I've heard," Klopp said ahead of Liverpool's Champions League opener against Napoli.

"There are a lot of good teams out there and you have to prove that [you are up there with the best] constantly.

"Last year, we were really good. I'm not sure we were the best team in Europe, but we were really good in the right moments and that's why we won the Champions League."
