1971 Intercontinental Cup

The 1971 Intercontinental Cup was an association football tie held over two legs in December 1971 between the runners-up of the 1970–71 European Cup, Panathinaikos, replacing European Cup winners Ajax which declined to participate, and Nacional, winners of the 1971 Copa Libertadores. The first leg was held on 15 December 1971 at the Karaiskakis Stadium, home of Olympiacos, since Panathinaikos ground was deemed unsuitable.
