Fabinho was signed by Fluminense when he was 18 and played 6 months for us, only for youth. Never been in the main squad.
It's unbelievable to see him now. He looked like a clumsy RB destined to play at 2nd/3rd division in Brazil. Not a standout by any means.
Then suddenly he's at Madrid B and got the chance of his life. A good agent nowadays does wonders - and the guy took the chance and made the most of it. Really impressive.
I'd focus on the left wing, his defending was a atrocious when I saw him play for us (2 or 3 years ago)
