Liverpool duo Philippe Coutinho and Roberto Firmino appear to becoming better acquainted on Brazil duty

Philippe Coutinho and Roberto Firmino

Philippe Coutinho and Roberto Firmino look to be bonding on international duty before the Brazilian duo return to Liverpool next week.

Firmino became Liverpool’s third most-expensive signing after he completed a £29m move to Anfield from Bundesliga side Hoffenheim in the summer transfer window.

The South American playmaker made his full debut in a goalless draw with Arsenal before he started their 3-0 defeat by West Ham United in their most recent game.

Coutinho, meanwhile, scored a brilliant winner in a 1-0 win at Stoke City in their opening fixture of the season before he received a red card against the Hammers.

But the Liverpool pair were all smiles as they were joined by their Brazil team-mates for a selfie, including Chelsea midfielder Willian.

Coutinho wrote on his Instagram page: "Leaving for Boston"

Dunga’s Brazil were unconvincing 1-0 winners against Costa Rica in their friendly at the Red Bull Arena on Saturday.

Brazil will face the United States on Tuesday in Foxborough, Massachusetts, as part of its two-game friendly American tour.
