Im sure De Gea does have a weakness or two, not sure that is one though. If he's not leaving his line at set pieces then he is being instructed not to for whatever reason, there is no way a keeper at that level consistently doesnt come out as would be told to when working on set pieces in training. Regardless, De Gea is a better goalkeeper than Lloris surely you'd agree....de Gea has a big weakness too.. he doesn’t leave his line and it costs them goals. The reason it won’t flagged up is because he doesn’t actually make a mistake by saying rooted to his line and he generally dives near to the ball as it goes in
