The Brazilian signed from Inter in January and has already managed a goal and two assists in his three appearances for the Merseyside outfit.
"Philippe has been brilliant," Pascoe told the club's official website."He is a quiet, young lad and it must be hard for him because he doesn't speak much English. But with Luis [Suarez], Lucas, Sebastian [Coates] and Fabio [Borini] you have Spanish and Italian, and he can speak that."
He added, "I'm not surprised by his impact so far as we knew how good a player he was. He's got a good eye, he's got a good awareness of where his teammates are and that's what he's picked up very quickly. He got two assists at Wigan. The one he crossed for Stewart Downing's goal with two wingers combining was fantastic, and his goal against Swansea was superb."
Pascoe has been impressed with Coutinho's ability to split defenses and get into the final third.
"He wants to get into the box and he wants to score goals. If the opportunity is there for a pass he will make the right decision whether to shoot or pass and that's the sign of a good player," Pascoe explained.
Pascoe is also happy that Brendan Rodgers’ style of football seems to be paying off, with Liverpool having scored 12 goals in their last three games.
"It's always hard when you implement a new style and it takes time to get used to it, but with the way the lads have been playing it has been fantastic," he said. "Daniel Sturridge and Coutinho came in January and they have gelled well with the rest of the lads."
"The lads have been fantastic and every day they are working hard on the style, the tactical and technical style of their game, and good positioning, pressing and passing the ball better."
