Supple is a fantastic talent also. He played today against Norwich and he looks to me to be a far better keeper than Doyle was at the same age (19). I reckon he'll be the successor to Given.
They both look excellent though. Logan is apparently pretty handy also though I haven't seen much of him. Good riddance Paddy Kenny.
Now all we need is a left back and another couple of central defenders and we're rolling.
