"I'm looking forward to a good time," Coutinho said in his post-match interview.
"I am very motivated.
"I want to work hard this year so that everything goes well on the pitch."
"We haven't had much time to train in pre-season, but we are improving," Coutinho noted.
"We are getting used to the way the coaching staff works.
"We still have a week to get off to a good start."
