They are a great side but the comparisons are unfair when you consider the changes in football to what it was back in the 60/70/80's.
It's the same when considering Messi/Ronaldo to Pele/Maradona You're talking about World 11's (sometimes even World Class squads of 25), better pitches, better (user friendly) matchballs, more subs allowed, far more stringent refereeing and laws on tackling. The great sides of the past were also restricted to 2/3/4 foreigners.
