The 1973 UEFA Cup final took two attempts to get going. The first leg was due to be played on the Wednesday night and did get underway, only to be abandoned after 23 minutes due to a waterlogged pitch. BBC had the coverage of the first leg, possibly on a Sportsnight Special delayed from the previous night. All I have seen is about a minutes highlights on YouTube.
The two sides came back the following night and the combination of John Toshack and Kevin Keegan was too much for the German side. The first goal saw Toshack rise at the far post to head back across goal, Keegan meeting the knock down with a superb diving header to open the scoring.
The lead was doubled on the half hour mark and it was the same combination. This time a floated free kick was headed down by Toshack for Keegan to poke beyond the keeper. The 3rd came around the hour mark, Larry Lloyd rising to power home a header from a corner.
The most crucial moment of the game saw Ray Clemence produce a stunning penalty save to preserve the clean sheet, and prevent Borussia from grabbing a vital away goal. Not until the 2nd leg would it be realised how crucial a moment that would be.
