Francisco Trincao's junior coach says Barcelona have chosen well in signing the Braga star.
The winger is currently on-loan with Braga after being signed by Barca in February.
José Carvalho Araújo coached Trincao for six seasons and told Maisfutebol: "Trincao is one of those we noticed made a difference from a young age. Now it is easy to speak, but I have trained him for six years and I know what I am talking about.
"He always showed an enormous capacity for work, what differentiated him was the way in which he faced things. For him, playing soccer is a pleasure, a joy, and that is essential. For Trincao it is like playing with friends on the street."
