Reyes is really working hard, he's an amazing player.
Yebda just came from an injury, so maybe that's why he wasn't totally fit.
I personally wouldn't field Jorge Ribeiro instead of Léo. I don't know what happened but there clearly is a problem between Léo and Quique, in their relation, it's not about the player's ability.
Imo, Jorge Ribeiro is a very good crosser of the ball and has a more accurate and powerful shot than Léo. However those are the only things in which he's better, in everything else and despite Léo's age, he is the better player. I mean, defensively Ribeiro is very limited and because he isn't by any means a very fast player (he can't recover his position very quickly) this exposes the defense on many occasions, e.g. Naval scored by exploiting the left side of defense and of course Luisão was sleeping, well most of the team was but anyway they attacked much more from Ribeiro's side, and so did Hertha.
Regarding Sidnei, he's a wonderkid. Seriously after watching his matches this season can you believe he's still only 19? The way he anticipates the play, the tackling, positioning and aerial ability make him an excellent defender already. If he continues to improve he has a great career in front of him.
More can't be asked to Cardozo, he entered well in the match playing well and was rewarded with a goal.
Still, we won and deservedly so but this team should know how to control the game when winning, they just totally slacked off, somehow thought the match was won and that almost cost us the win. They still have a lot to improve, but still glad we won of course.
Sorry 'bout the long post
