Norwich City must halt the best striker in the world and find a way past the best keeper when they challenge Premier League champions-elect Liverpool at Carrow Road.

The Reds have dropped just two points in a remarkable season that started with a 4-1 opening night home victory over Daniel Farke's newly-promoted Canaries.

The European and World club champions need six league wins to clinch a first domestic title in three decades, ahead of Saturday's return visit to Norfolk.

Key to such dominance has been the best-in-class form of Alisson Becker and Roberto Firmino, in the opinion of compatriot and former world player-of-the-year Kaka.

"Alisson is the best goalkeeper in the world right now, and Firmino, along with Luis Suarez are the best strikers in the world," said the Brazilian, speaking to Sky Sports.

"Firmino understands his place on the field and changes his position. He doesn't stay in the box the whole time, he comes and gets the ball and creates the plays.

"For me, as a Brazilian, it's really good to see them having this great success in the Premier League.

"It shows that Liverpool are in very good shape and have a very good coach and players. Jurgen (Klopp) is a pioneer coach. He's not afraid to change and try something different."

Klopp's influence means Norwich can forget any whiff of complacency this weekend, according to Reds' right back Trent Alexander-Arnold.

"That's how we need to think and that's the way we need to be," he said, quoted in the Liverpool matchday programme. "That's the message the manager drills into us on a daily basis: that nothing's over yet, there's still a long way to go.

"We're just over halfway through the season, so it's important for us to keep our heads, keep focused and keep our mentality the same. That's what's been working for us, so nothing should change.

"You can see on the touchline and in his interviews before and after games, he's so passionate about the match and passionate about winning. We see it every day in training and it's important for us that he gives us those messages.

"He's not only just helping us win, he's giving us the mentality to be able to overcome any circumstance during a game."
