"A starting point could be that our opinion is perhaps coloured by the volume of football on TV. If a corner only leads to a goal 3.2% of the time it’s inevitable that most corners aren’t going to leave a good impression and the more of them we see the more entrenched that negative view is going to get. And then there is the oft-parroted view that professional footballers trousering loads of cash at the very least should be able to beat the first man. This is where there is a serious misunderstanding by many fans about what constitutes an effective corner. There is a huge difference between phoning one in and delivering a dangerous one."
I've always considered it a strange one. The manager would want the the tried and tested method of whipping the corner in aiming to just miss 'the first man', but the fans would seemingly prefer a more consistent corner lofted towards the penalty spot (even if it will result in less success over the course of the season).
