Barcelona have been strongly linked with attempting a move for the playmaker, something that has been endorsed by Brazil coach, Tite.
Coutinho bagged 13 goals for the Reds last season, and was rewarded with a new deal that will keep him at the club until 2022, which is something the 25-year old is committed to.
"Talking about this [Barcelona] is complicated," said Coutinho via The Sun.
"I have a contract with my club and it is long.
"So my focus is on the present and the national team. My focus is here."
