Real Madrid stretched their sequence without defeat to 40 matches in all competitions on Thursday night, breaking Barcelona’s Spanish record in the process. But in European terms they still have a way to go.
Celtic set the benchmark exactly 100 years ago, their run of 62 games including two in a single day at one point! All of those fixtures came in the league, as did Union SG’s tally of 60 in Belgium between 1933 and 1935.
The best record since the advent of European competition goes to Benfica. Under Lajos Czeizler and then Elek Schwartz, a side featuring Eusébio reached 48 games unbeaten between December 1963 and Valentine’s Day 1965.
