Think there’s long been a bit of a myth around the true value of corners. A study was done a while ago based on 10,000 corner kicks. Of the 10,000 kicks analysed just 1,362 led directly to an attempt at goal, and of those attempts only 182 went in. That means that only 1.82% of the corner kicks analysed ended in goals, so you could have 50 corners and if you scored once - which would mean a conversation rate of 2% - you’d be outperforming the statistical average.
Not to say they’re unimportant or that you can’t improve and perform well above the average, of course. Merely offering a little insight into the real value of a corner kick versus what we often think as spectators.
