I honestly think Bruno Fernandes' stats on his FBref page illustrate the player he is pretty well:

He's a creative freak who values chance creation above pretty much everything else. He gets on the ball a lot, he attempts to play the ball forward a lot, and because of that his expected assist levels are sky high. He is top tier percentile in these areas.
With the above in mind, he has terrible ball retention and passing accuracy.
He is a below par dribbler/carrier of the ball, opting to pass rather than take players on in isolated areas of the field.
He has marathon runner level stamina and endurance, and as a result his defensive stats in contrast to other attackers are pretty mad.
Depending on what you seek in an attacking midfielder, you will either value Bruno as one of our best players (chance creation, doggedness, endurance etc.), or someone who is a big flaw (inability to play a calmer game, retain the ball a little better to sustain attacks rather than all or nothing plays, show more composure etc.).
