Okay I fight the midfield battle a bit different to TITO, but here we go. There's something that's driving my crazy since 1982 when everyone started raving about that magic square and how brilliant it is.
Here's my theory...
... there is no 4vs3 numerical advantage in football, it simply doesn't exist. Sounds strange? I'll try to explain, so if you're into tactics, go with it, even it might seem idiotic at first. (You can still call me a fool in the end, I don't mind
).
Numerical advantage in possession means, I've always a free passing lane available, right? That's the idea.
So there's
2vs1, well, no need to explain anything, obviously defending alone against 2 sucks.
There's
3vs2, we all know the 3 man midfield discussion all too well, right, but I'll love to use pictures, so here is one.
Whatever the 2 defenders try to do, there's always a passing option available or the player with the ball can move forward himself. So you need a 3rd defender. Here you go, midfield domination gone.
Okay, we're getting somewhere, now we add the 4th midfielder in possession,
4vs3 now:
It's still only 3 defenders, but Defender 1 is closing down the DM in possession while at the same time blocking the passing lane towards the 2nd CM. The angles are so small, that the 4th midfielder can't move anywhere to actually be available for an open pass, so it's still up to one of the 2 midfielders close to the ball to find a way to become available.
Now it gets really interesting and I hope it shows why the magic square is so vulnerable against pressing, the 4th defender comes into play.
The 4th defender will create a 1vs2 situation which means the DM will be forced to pass back to one of the defenders or try to kick it forward and hope for the best. The 4222 lacks width, his fullbacks need to be careful because the wings are already outnumbered and if they move forward to build a triangle out wide in midfield, my fullbacks can cover them.
That's really the idea behind what I called 'hunting for the ball' in my defensive tactics in the OP with Cruyff as my 4th defender while Forlan stays with the centerback closer to the ball. You need triangles to play through pressing, but you can't build triangles in a 4222. If you don't believe that actually works, well them I'm in trouble, big big trouble. (It works though, just watch some of the videos I linked to in the op).
