Liverpool manager Jurgen Klopp has hit back at recent criticism of his side ahead of Sunday's Merseyside derby against Everton.

The Reds have made their best-ever start to a Premier League season and are still unbeaten after 13 games, but find their Champions League hopes hanging by a thread following defeat to Paris Saint-Germain on Wednesday.

Liverpool have scored 15 fewer goals so far than at the same stage of last season, but they also boast the best defensive record after 13 games of a campaign in the club's history, and Klopp insists that it is natural for the balance of the team to shift slightly.

"When everything is brilliant and we score goals, you always ask about defending and how we can fix that. We fixed that, kind of, and it always happens that, initially, you lose creativity. That is completely normal," Klopp told reporters.

"I can't say to the boys, 'We've fixed things at the back but we're not doing enough offensively.' That would be crazy. Bringing one player in would change everything? That's bullshit, and you know it.

"Really, if people cannot enjoy our football then I can't help them. I get constantly confronted by people saying something is missing. Of course it could be better, but it's not because of one player. In the games we have won we were always the better side. Not one lucky game. That's rare."

Liverpool host Everton at Anfield on Sunday night looking to extend their record unbeaten streak against their near neighbours to 18 matches.
