It feels like there have been quite a lot of players recently who have promised so much but, for whatever reason, just haven't turned into what we'd hoped.
In the last 2 or 3 seasons alone we've had the following disappointments:
Richard Sadlier - injury
Sean Thornton - p1ss head
Liam Miller - badly advised move
John O'Shea - lack of confidence? Not good enough for MUFC?
Steven Reid - injury / crap manager in Souness
Colin Healy - injury
Thomas Butler - went mad
Paul Tierney - never even made the first team despite all our hype
Graham Barrett - scored on his Irish debut
Joe Murphy - Not good enough? Great start at Anfield but then...
Alan Lee - 15 goals in one season in Div 1 but nothing since
John Thompson - great year at Forest when they nearly went up. Nothing since.
All but Tierney & Thornton have senior caps.
Who else is there?
There's also a whole load of players who have figured in the Irish underage sides who have been released or dropped down to the basement divisions to play.
Personally I still think O'Shea, Miller & Reid could come good. Less so Thornton despite all his talent. Healy - who knows?
