Give him time i trust him.
Look how fast he answers the questions. He can think fast and seems to have a high IQ. He will be the brain of barcelona in 2-3 years. Imagine Dembele he would need a minute for each question (Dont take this statement too serious).
Trincao can speak three languages, Dembele can not even speak Spainish. Clearly show who is better.
I don't know why so many people are harsh on him, he has some good attributes and can be a useful player, personally wanted him to go on loan so he could play more minutes as minutes = development. His two main issues are a lack of speed for the modern game and terrible finishing (possibly worse than demebele's, to think that's even possible).
I think he will be a good finisher, just unlucky so far. Always strikes the ball well.
