Coutinho has caught the eye in recent games.
"I've been very impressed," Sturridge told liverpoolfc.com. "He sees things very early, he's got great vision. He's a very skilful player and he's got a powerful shot on him also.
"I think it'll take time for us to see what he's really capable of doing because he's come from a different league, but he's already showing that he's got a vast amount of qualities.
"The best is yet to come from him but you'll see that he's a very, very special talent."
