Sound, have you watched the reserves/youth team?
I try to give the rezzies a watch and used to go the youth cup matches but if often conflicts with my pub activities.
I'm not the oracle that alot of people on here are but I watch enough.
Quick summary:
Insua: Could challenge Riise for a place now, but then who couldn't. If Rafa was looking at Heinze, then Kaladze, then continuing to play Riise at left-back I wouldn't hold my breath waiting for the lad to break into the first team.
Anderson: Starting to tire for Swansea but could step into our first team any day of the week (again this isn't an indication of how good he is, more of how bad we appear to be of late), definatley the bright light on the horizon.
Leto: Plays good for the reserves, looked very over-awed against Marseille. Rafa may give the lad one more crack at the first team, but I think that'll be it. The lad could make it somewhere eventually, but to look good in the reserves isn't enough you have to be great (see Neil Mellor).
Plessis: Lad looks good. Can tackle, can pass, but unfortunatley he's at centre mid. Centre mid has been "locked" for many years to come.
Nemeth: Looks very good but has only had a few games, lets not get carried away yet.
Like I say though I hardly get to watch them anymore so take my opinions with a pinch of salt.
