Here he is with another generalisation.
2021 AFCON - 52 matches. Number of 1-1s? Five. Just under 10%.
2019 - 52 matches, six 1-1s. Just above 10%.
2017 - 32 matches, five 1-1s. 15% roughly.
2015 - 32 matches, ten 1-1s. Just over 30%.
Unless you forgot about the previous 3 tournaments then you have a point.
But yeah, 'full of boring 1-1s'.
Quality of football is improving nonetheless.
