The 21-year-old opened the scoring in the 3-0 triumph over Thailand on the club's tour of the Far East and Australia, his third goal of pre-season.
Coutinho pulled the strings in a comfortable victory, and Rodgers admitted that the forward is the kind of player he loves to watch.
"Coutinho had me up off my seat," he told the Liverpool Echo. "He's a player you would pay money to watch. He's just a delight on the ball."
"The idea was that Aspas would give us another dimension up there and he's done that," he continued.
"He's a very effective player. Sometimes he's not always easy on the eye but when you actually monitor how efficient he is - he creates goals and scores goals.
"It was a lovely touch into space by him for his goal and he finished really well. Then he showed good vision to set up Stevie, who finished magnificently."
