Watched Gaston close up last week. His first touch is outstanding, but I was getting annoyed that he was finding space and making himself available, but team mates preferred the easy option of checking back all the time. He does need to knock the fancy flicks on the head though, they didn't come off for him a couple of times last week, and cost us possession in dangerous areas of the pitch.
He is a quality player who is just going through a bit of a rough patch at the moment. Stick with him, class is permanent.
