The promising youngster impressed on loan at Espanyol in the second half of the season and is now eager to make his mark at the Nerazzurri in the 2012-13 campaign
The Brazilian was farmed out on loan to the Liga side for the second half of the campaign after struggling to secure regular first-team action at the Giuseppe Meazza, and the attacking midfielder is keen to begin working under new coach Andrea Stramaccioni.
"I am a new Coutinho after my spell at Espanyol. I got a bit depressed at Inter because I did not get much playing time," Coutinho told La Gazzetta dello Sport.
"That won't happen again, though. Getting regular first-team action was vital for me.
"I really like Stramaccioni's football philosophy. He's always ready to talk with his players, and I hope to develop under his guidance.
"He gives you a lot of freedom in attack, although you obviously have to help out in defence as well.
"I have to think about myself now and do my utmost to secure a spot in the first team. I want to succeed here."
The 19-year-old joined Inter from Vasco da Gama in the summer of 2010 for a reported fee of €4 million.
