https://www.tifofootball.com/video/are-corner-kicks-becoming-irrelevant-in-football/ A new article just came out about decreasing threat from corners. The article states that since 2000 in the big 5 leagues 40% of all direct corners do not clear the first man, 3.3% of corners eventually result in a goal, but interestingly only 1% of direct corners lead directly to goals. This implies that second chances or short corners result in ~70% of all corner goals. If failure rate at the first man is 40% with direct corners then short corners become a much improved method to create opportunities even if the failures are sometimes painful to watch. https://www.footballwhispers.com/blog/revealed-premier-leagues-corner-kick-kings This article discusses the risks of counter-attack to attacking teams on corners. Essentially every corner results in approximately a .4% of conceding a goal on the counter. This further eats into the value of corners. https://www.footballwhispers.com/blog/revealed-premier-leagues-corner-kick-kings This article brings up an really interesting statistic about which teams are successful at scoring and defending corners. Interestingly having players with high ranks in aerial duels won did not directly relate to success at corners either attacking or defending. It gives the example of Burnley who had 4 of the top 15 players in the league for aerial duels yet scored 0 goals from corners and Leicester City who with Maguire, Huth, and Morgan at the back conceded the third most from corners in the 17/18 season. It seems that the defensive systems and ability to work the ball into the box offensively were much bigger factors in success than having aerial dominance.
