After the thrashing of Barcelona and Real Madrid there’s been a lot of discussion about the ascendancy of German football and the decline of Spanish football. But how surprising were these results and is there any chance the Spanish teams will be able to strike back?
Likelihood of First Leg Result
The first question relates to the unlikeliness of the result. Before the match was played the probability of Bayern Munich having a goal difference from the first leg greater than or equal to +3 was 8.9%. When we look at the probability of a +4 goal difference the probability is reduced to 2.7% but this is partly due to the generally low scoring nature of football. The chances of Dortmund finishing the first leg with a +3 goal difference was 8.3%. These results were not quite so unlikely as commentators have made out although the most likely result for both semi-finals would have been a 1-1 draw.
