Luis Suarez and Daniel Sturridge have netted eight Premier League goals apiece this season to sit at the top of the scoring charts alongside Manchester City's Sergio Aguero.
Coutinho will be charged with the task of ensuring that both men add to that return over the coming weeks, with the Brazilian playmaker having made his first start since September in Saturday's 4-0 mauling of Fulham.
He is convinced there is plenty more to come from Liverpool's deadly strike duo, and the squad as a whole, as they look to build on a productive opening which has them sat second in the table.
"It's incredible. As I've said before, they're great players," Coutinho told Liverpool's official website.
"They're always on the move and scoring goals and I'm happy to play with them.
"They make our work moving forward easier because they're always looking for space, and it's easier to pass them the ball.
"But it's not just them in the team, there are other great players and I'm very happy to be part of the group. It's an excellent team."
Coutinho moved to Anfield alongside Sturridge in January, and he says the England international has helped to lift team spirit on Merseyside.
He added: "He's an excellent person. He's always playing around with me and the other players, and he's fun to be around and a great player.
"Everybody on the team gets along very well when they're off the field and I think that creates a greater union between us and makes us stronger on the field."
