Liverpool boss Jurgen Klopp admits Luis Diaz will be crucial in the title race.
Klopp believes that his Colombian star is benefitting from having had to come straight into the side on his arrival from Porto and is under no illusions as to how important he will be to the Reds' hopes this season.
Klopp said: "He had to play immediately because two boys were at the Africa Cup of Nations, so that helped him settle in. That gave him immediate confidence. It's his quality, his talent, his skillset. He's a really good player.
"We knew it before and when you're really good it's easier to settle in.
"He has this special thing: He can score from outside the box, which for a striker is really important. He's very, very important for us."
