1. Relatively good first touch when his chest is involved, not so good when he is trying to bring the ball under control just with a foot.
2. As for losing the ball - you need to read more carefully what I've said. Namely that his poor ball control leads to us losing possession. I haven't said he loses the ballbecause of that
too often. The point being he doesn't need to try tricks and magic stuff he just can't do. Also, I am extremely surprised to hear a player capable of these (below) has "very good technical ability":

Yesterday there was another flick he tried while being next to the left touch line and failed as well but can't find a video for it.
3. As for his dribbling - yeah, van Persie and Kagawa are much worse... (sarcasm). Knocking the ball past the opponent is not dribbling (meaning Valencia too isn't a dribbler).
4. As for goals you're bringing up his goal tally for just a few games, I am talking about his whole last season.
5. You still haven't said anything about his passing and crossing, simply because it doesn't suit you... what about that?
