The ball is live, the team taking the short corner have no obligation to open up and be more expensive, that's on the other side to work out. Could argue what we did against villa by playing on our own goal line goes against the spirit of the game, stifles play, stops creativity etc, maybe that should be penalised in some way as well? For me, it's not a problem. Football is about working it out and finding solutions, more laws means more complications and less enjoyment.
