Chelsea v Real Madrid, Friday 21 May 1971, European Cup Winners' Cup final, Athens
Chelsea skipper Ron Harris and his counterpart Francisco Gento of Real Madrid lead the teams out at the Karaiskakis Stadium in Athens.
The simple, elegant trophy the two teams were competing for glistens pitchside atop a Greek flag.
Having exchanged pennants, Harris and Gento contest the coin toss under the supervision of Swiss referee Rudolf Scheurer.
Peter Osgood (left) celebrates scoring the opening goal 10 minutes into the second half. Keith Weller is the man joining in.
Unfortunately for Dave Sexton's Chelsea, the Spanish side equalised in the last minute to take the final to a replay.
The teams reconvened at the same stadium 48 hours later, and here David Webb (number six) and Osgood (nine) are pictured in the buid-up to John Dempsey's opening goal, a fine volley. The defender is between the two Real Madrid players in the background.
Osgood doubled our advantage before the break and though a Real Madrid goal 15 minutes from time set up a nervy finish, the trophy was ours. Here captain Harris is chairlifted by a gaggle of ecstatic team-mates.
Wearing slightly more clothes but with no fewer grins on their faces, the players gather round the trophy at a press conference celebrating the triumph.
Many Chelsea supporters who had travelled to the Greek capital had to return home after the first game. But when the squad returned to London to parade the trophy through the streets of Fulham and Chelsea, every Blues fan got a sight of their heroes. The parade finished at Fulham Town Hall where a reception was then held to toast the momentous victory..
