Agreed on Cuellar, he's massively underrated. I'd start him ahead of Collins or possibly Dunne considering his recent form. Also, with Clark's recent pushing for a starting place Dunne will need to play well to keep him out when the midfield returns.
Really don't agree with McNulty's analysis of Friedel though. He saved us from going 4 down late on, and he has made admirable rescue jobs all season. He's still one of the top keepers around, and I wouldn't swap him for most.
