When done right it is a great tactic. I was watching the Leipzig v Bayern game yesterday and some of the suicide passes to players inside their own box were breathtaking, but they somehow managed to pull it off. It's quite exciting to see defenders ping the ball around when the opposition players are so near. They must spend a lot of time doing drills for this sort of thing, but the German teams do get hold of their 1st team players when they are very young, so good technique and discipline is instilled into them.
