Forgotten prospects

Just reading some articles on football365 about one game wonders and my mind drifted to some of our former academy players that never made it with us for whatever reason.
I remember Ahmad Benali being highly rated and had high hopes he'd become our home grown playmaker for years to come.
Just googled him and surprised to find out he is still only 26 and has carved out a very respectable career in Serie A. Apparently Wast Ham and Southampton were interested in him last summer. He also looks a bit like Dave Silva nowadays.
Anyone else remember any other promising players that seemed to just disappear?
