I remember hearing his name years ago when he first moved from brazil to europe and thinking, another brazilian wonderkid, another mercurial attacker, another player that we would never in a million years attempt to sign because, simply, these weren't the types of we'd ever go for...
fast forward 5 years and every club in the league is watching his performances enviously. I think we're now seeing a player who just knows he's better than his opponents and consequently tries to dominate as soon as the whistle blows.
He also now has a perfect supporting cast around him, with pace and technical skill who he can trust, in stark contrast to recent years.
