Liverpool are a better side with Roberto Firmino, according to left-back Andy Robertson.
Andy Robertson says he isn't sure there is anyone who has the 'work-rate, technique, goals and all-round play' Firmino has in the Reds' side.
Liverpool beat Burnley over the weekend as Chris Wood's own-goal and strikes from Sadio Mane and Firmino handed the Merseyside club three points.
Firmino became the first Brazilian to score 50 Premier League goals after his heroics against the Clarets, and Robertson hailed his teammate as "world class" following their victory at Turf Moor.
"With his work-rate, his technique, his goals and his all-round play, I don't think there's anyone like him," the Scotland international told UK media as Goal reported.
"People will say there are better strikers, but for me what he does is so important to our team. We'd be lost without him. He's world class."
Robertson also praised the 27-year-old's defensive attributes.
"He does everything, and that's the beauty of Bobby. He can do it all. He's our first line of defence, and I've not seen anybody better at doing that," he said.
"He presses the defenders and doesn't give them a minute. He comes back and nicks the ball in midfield for us.
"He's so important defensively for us, then he goes up the park and scores goals and makes assists. That's what we need him to do."
Firmino has scored two goals and registered two assists in four league matches for Liverpool this season.
