Since the friendlies last season, when Munir and Sandro came to the fore, I always rated Sandro higher than Munir, though most were going gaga over Munir. I think Munir is a more skill/technique based player, but from whatever I have seen of him so far, I don't think he's got that extra level to make it in the first team.
Sandro is a more direct, center forwards forward kinda guy. Strong, not afraid to shoot. He's a breath of fresh air in the team, I think he can be really useful. He is the only B team player I think we can seriously count on this season. (Maybe Samper, but not sure how many minutes he will get either)
