If two players jump for a header and one of them wins the header but the other one gets knocked out by the mid air collision. Is that a penalty, a foul, a red card? Nope.
In my opinion, if the keeper calls it and you are dumb enough to challenge him for a ball like that in mid air, a ball, that you are never going to win, you are only endangering yourself and deserve to get clattered. And should get no sympathy.
That keeper has just set a example now in his first game, high balls in there are his and feck you if you think you're getting near one. Can almost guarantee nobody will go a for ball with him now once he calls it after seeing that.
