This was quickly corroborated by a number of journalists and news outlets, with Reds’ chief executive Ian Ayre said to be flying to Chile to finalise the deal.
Firmino scored seven goals in 33 Bundesliga appearances for Hoffenheim during 2014/15, creating 69 chances, according to Squawka.
BBC Sport’s South American correspondent Tim Vickery speaks highly of the attacking midfielder.
“He was unknown to nearly all in Brazil when first called up last November,” Vickery tweeted. “Since then he’s played 9 games for Brazil, 5 of them as a sub, scoring 4.
“I’ve been very impressed, mobile and versatile, up top or dropping off, shoots well from range and can score poacher’s goals, combines well.
“A shy lad – Brazilian media laughing at his press conference today when he answered 18 questions without saying anything. Has adapted well to Germany, clearly, so why not Liverpool? Bar higher now, though.”
The news has delighted Liverpool fans around the world who are keeping everything crossed the deal is completed without any hiccups.

I'm really liking the look of our transfer window so far. The free agents have all been practical signings, and Firmino looks a bit of a gem

We're paying £1m more for firmino than Everton did for the guy who gets benched on international duty by Origi ???

Held off talking about Firmino to #LFC in case it didn't happen. Now it appears safe, must say I'm delighted! Huge step in right direction!

Firmino the type of signing we should be going after tho. Get them before the super rich are sure. Lacazette next please and keep Sterling.

Liverpool, provided they pull off the Firmino deal and sign a forward, Bacca say, could be devastating on the counter next season.

Roberto Firmino clocks in an average of a goal/assist for every 87.4 minutes of game time for Brazil. #LFC
