Manchester City boss Pep Guardiola had a lot of praise to offer his opposite number at Liverpool - Jurgen Klopp.
The two men are very familiar with each other, having battled for the Premier League title in recent seasons.
The Citizens are top of the table this term, but Guardiola is a huge admirer of everything Klopp has achieved in the game.
He told reporters: "A lot [of sympathy for Klopp's current circumstances].
"What he produces in world football is exceptional. I say many times now, last season and in previous seasons in Germany.
"His philosophy makes football attractive for all spectators. He always produces joy to the fans, to world football, there's no doubts about this.
"We all have good moments and bad moments, no manager or club can sustain seasons and and season seasons to win and win. It would be boring.
"Sometimes you have to lose, to realise. I speak personally, I don't say for my colleagues.
"Sometimes it's good to lose to realise how difficult it is everything. When you come back and win games you get more credit and you are more satisfied for what you have done."
