Welcome,
I think that after he had his big injury, he lost essentially all of his speed (which used to be his number one advantage). Used to be a very good dribbler, but after being ordered to play more disciplined football by his coach at the time, he toned down on that. Recent highlight videos probably won't show much. However, he's also played so rarely in the past year that he doesn't exactly have a lot of minutes to highlight...
Others around here would disagree with me, but I think he's kind of washed up. Seems to constantly be in conflict with the team's administration or coaches. Seemed to agitate to leave (for Portugal and now back to Brazil) very quickly after we signed him. I don't think he's the kind of guy who can be convinced to give his all to a club he doesn't care much about.
The big positive - I think he's friends with Leo Matos, who most of us adore. He might be a good influence on the kid.
