Altough Alan Hansen did play for Scotland I was gobsmacked when I found out that he only got 27 caps.
Tommy Smith only got one cap to his name.
My pick would be Jimmy Case.It's ironic that we are discussing some quality LFC players who never got international caps, yet Salif Diao captained Senegal in the World Cup, and Bernard Diomede actually got a World Cup winners medal!!
A few years ago I took my family to Anfield for a Mothers Day Lunch in one of the Centenary Stand Suites. Alan Kennedy and David Johnson were there as after dinner speakers. I always remember Alan saying that he and Kenny Sansom won 90 caps between them...
And then we'll get 4th as well and everyone in the whole world can do one.
