PSG captain Thiago Silva has also made the Seleção squad for the tournament and has backed Coutinho, claiming he has looked much happier on global duty.
"I have not had a good season", said the 26-year-old.

The little Brazilian consistently improved to become a star at Anfield before opting to leave for Barcelona.
