I really don't know what people are seeing in Sammy. I know it's early days for him but so far, despite his speed and awkward dribbling style, I've seen no indication of him being first-team material yet.
He's kind of a surprise package right now, have him on the right cutting in and causing a bit of havoc, let him roam a bit. Give him freedom to express himself similar to Ben Arfa and see what he can do I say.
