"He [Firmino] is a player who would be on the agenda of any Brazilian club, for his quality, for everything he has done as a footballer, for his commitment," Corinthians football manager Alessandro Nunes told reporters on Monday.

Firmino, who has 55 Brazil caps, has declared a desire to play for Corinthians - the team he supported as a child - if and when he returns to Brazilian football.

He has also been linked with Arsenal, Chelsea and Tottenham, among other suitors.

"Without a doubt, if there were a possibility of signing him, any club would be interested," Nunes said. "In my opinion, he still has the quality to play on the international stage."
