the 4-2-4 has the potential to rape all the small teams. It's easier to control the ball against them and if we can do that, we'll have 4 players up front with Pirlo pulling the strings with more space around him because we have stretched the team wide. If we don't get caught on counters we have the potential to rack up alot of points in those games.
Against bigger teams we will need to adapt. But I don't believe any team should just play 1 formation all year, that's stupid.
