I think there are two issues here in the stadium: first of all, the behaviour of some supporters. Drunkenness has been part of crowds for many, many decades. That's not an excuse, of course, for the way some people behave. If people behave in a way that is obnoxious or breaches public order, then stewards should be informed and those people should be warned, and, if they don't take heed of the warning, removed from the ground. The second point is that many people complain that they're up and down on their feet all the time as people go back and fore to the bars in order to buy alcohol. It seems to me that people don't need to buy alcohol throughout the game in order to enjoy the game, and I think this is an important pilot—if I can call it that—that's being pioneered in order to see what the effect will be.
