Let's get one thing straight: there are sports such as football, and there are hobbies like tennis. Never should the two meet. The result, as is always the case with inbreeding, will look a lot like Frankenstein. Hence the instinctive wince that afflicts football fans when pundits refer to two or more successive headers as 'head tennis'. Players can use any part of their body that's not an arm or a hand to shunt the ball in the desired direction, hence it's not that strange to see the ball bouncing around in the air for a couple of minutes. In fact, it provides a welcome change from misplaced passes and duff corner kicks. Once again, this is not tennis, okay? This is a serious sport, not a harmless Sunday morning hobby. Adjust your cliche accordingly.
