Can told the official Liverpool website: “He plays like a lot of Brazilians – he’s a fighter, and technically very strong and capable, and that can only help win matches for us.”
Firmino has become the third Brazilian player in the current Liverpool squad joining Lucas Leiva and Coutinho.
The attacking midfielder completed his transfer from Hoffenheim to Liverpool last month for a fee that could reach as high as £28 million.
The 23-year-old provided a total of 36 assists and scored 49 goals for Hoffenheim in 153 appearances in all competitions during his time in the Bundesliga.
Firmino joins the likes of Joe Gomez James Milner, Adam Bogdan, Danny Ings, Nathaniel Clyne and Christian Benteke who also joined the Reds this season.
Meanwhile Can joined the Reds on a £9.75 million transfer last season from Bayer Leverkusen and established himself as a first team player despite a lengthy injury before the turn of the year.
The 21-year-old is expected to start for Liverpool in their Premier League opener against Stoke City next week at the Britannia stadium.
