The Dutchman played with the Brazilian at Hoffenheim, and rates him very highly.
Dutch forward and former Liverpool player Ryan Babel has been discussing Hoffenheim's Brazilian forward Roberto Firmino on Twitter, with Sky Sports stating that the Reds have agreed a deal with the 23-year-old's club.
Firmino is currently in Chile with his national side taking part in the Copa America, and Babel, who played with the Brazil international in the Bundesliga for 18 months, said that lots of people have been asking him on his opinion of the attacker.
Babel's comments pose an interesting question, with the two Brazilians both happiest playing in a classic number 10 role.
With Coutinho one of the players of last season in the Premier League, clearly Bredan Rodgers has a plan in mind of where to utilise Firmino, without dulling the input of his compatriot.
Is this a solution to the possible Firmino problem?
Though Coutinho plays best at the tip of an attacking midfield, he has been utilised on plenty of occasions on the wings at Liverpool, more often than not on the left hand side with Raheem Sterling on the right.
For large portions of last season though, Sterling was playing up front, and this is something that doesn't need to happen if Liverpool sign Firmino, not to mention any of the many other strikers they are rumoured to be chasing.
Firmino can operate up top if necessary, and is almost certainly a more accomplished striker than Sterling, but with doubts surrounding the young England international's future, it may be that Firmino is set to take the attacking midfield position, with Coutinho then employed on either wing.
On the other flank, Liverpool could continue to persevere with Jordon Ibe or Lazar Markovic, or bring in another player to play out wide.
