We have been talking about his potenial for years. He started playing with the first team around 2006, got many chances, but didn't show plenty of improvment. He isn't reliable on the wing, doesn't apply as much pressure on opponents, doesn't tracking back, and you need a stay home Left back behind him if he is starting, otherwise that defensive line would be in big trouble. I do like Pepe's more than Gio to be honest on the wing, Pepe would do the dirty work that none would like to do, he isn't as technically gifted as Gio, but he is miles ahead of Gio tactical wise. He is more discipline than Gio.
Gio is already 23, he needs to prove his worth and put together some consistant performances, over along period of time. There are somethings won't change, too small so defenders usually get him off his game easily by getting physical. His crosses aren't world class too, I would believe he might be more lethal as a trequatista, since he has the close control, nice first touch, and could place the ball nicely on each side of the goal. Maybe him being close to the box would make him more effective, better than drifting away to the wing and just get lost in the shuffle. Who knows, but I wouldn't mind having him as a SS, so his laziness and not wanting to track back, won't hurt the team as much
