Thing is, we're limited to one formation now, because Camo's absence. I don't see why we couldn't try Rossi on that right flank for half an hour. It's got nothing to do with overrating them and throwing them all in replacing anyone, but simply giving them a shot when in trouble due to injuries.
We shouldn't just replace our first team players with these youngsters, just because they're young, but what's the point in having a youth team when you never use it for the first team?
