It was easier* to win the European cup back then (not taking anything away from Forest's achievement, but there would have only been 4 or 5 top clubs in the competition, now there are probably 20 odd top teams in it.)Same here, not many English teams have done it, not even Manchester City with all the cash they have yet, possible they go back-to-back this season, but not many teams apart from the very best go back-to-back to win that trophy and Forest have.
* for the champions of England.
