The pair are able to communicate in Spanish, thanks to Coutinho's spell on-loan with Espanyol.
"We always communicate in Spanish on the pitch - I spent six months on loan in Spain so I can get by quite well.
"Suarez is a fantastic player and it's an honour to play with him. Together I hope we achieve great things for Liverpool. He's excellent, always on the move during the game, and helps you open the defence more easily."
