The sporting and financial security that exists in todays Champions League, with its group stage, was not on offer then in the European Cup, which was a straight knockout tournament like the FA Cup, says Harry Philp, a sports business expert at financial advisory firm Portland Advisers.

This knockout format was contrary to the interests of major clubs in Italy, which hosted the top league in the world at the time, and of the two Spanish giants, Real Madrid and Barcelona.

For these clubs there was a financial consideration around playing more games, and naturally there was also the sporting consideration of going as far as they could in the cup.
