I did post one theory 1000s of times:
1. people here are usually commenting ONLY on how a midfield plays (moving off the ball, static, possession, direct, technical, less technical etc)
2. but not too many are commenting about attacking options like scoring in different ways
No offense to anyone, but I don't think that Barca would be able to break this Atletico's bus tonight.
We would pass the ball through the ground all the time and pass to Messi.
Which is very easy to neutralize.
On the other hand, how many "lucky" headers has CR7 scored in CL knockout rounds in the last 6 years?
Crosses and headers are ugly.
I am not saying that we should cross ALL THE TIME.
But it is a very strong option.
Ideally, our team would need classical Barca's attack on the ground and some crossing+header options in the box.
When the opponent like Juve/Atletico parks the bus, too often headers are the only way to create havoc in the box.
They are losing because the opponent has SEVERAL different attacking options to break their bus.
Barca would struggle to break their bus.
We would just pass around the box and try to break them through the middle and Messi would have been surround by 4 defenders at the edge of a box.
On the other hand, 4 players can't man mark when you throw a cross...
