Coutinho also admitted that he cannot become the best in the world while in the shadow of Lionel Messi.
He is expected to inform Barcelona of his decision within the next month.
Last month, Coutinho was told by his teammate Gerard Pique to buck up his ideas.
"Come on Phil, you're not plugged in," Pique was heard shouting after Coutinho was dispossessed during a warm-up exercise in training.
The Spaniard later said "Obviously his cost was very high so that means there are more expectations of his performance level. It is what it is.
"We have to accept the reaction of the fans because they are our followers but from the inside, we have to give him our support. We need him at his best for the end of the season and I'm sure he will be."
