I love hearing about how the players in any sport were so much better than their modern day counterparts because they played more, or played hurt, or played in worse conditions ect.
The simple fact is no matter how great the heroes of yesteryear were today's players would run circles around them. I am by no means saying players from those days weren't good players but I'd be willing to bet Leicester or Sunderland would dominate teams from 40 years ago.
I'm pretty sure the Liverpool & Leeds teams of the mid-late '70s would tear last seasons' Leicester a new one!
...do me a favour!
...not to mention a certain D.Mackay 10 years earlier!!
They'd have 'em for breakfast... shit them out, and eat them up again!
