Remember, Paul Lambert wasn't even rated as a player when he was at Motherwell, (Did he get picked for Scotland in that time?)
Motherwell played Borussia Dortmund in a Uefa cup tie, and Ottmar Hitzeld saw him as a player and signed him up. The following year, Lambert was part of the Dortmund team that won the Champions League. We do have talent, but we don't recognise it. After that, Brown had Lambert as a regular.
Our current bunch of internationalists are under acheiving.
Strachan walked from from Middlesbroough when it wasn't working out, why not Scotland ?
