The details, no, I can't, I'm a mere armchair viewer!

The basic concept though, is about space and time. You look to create these by 'luring' the opponent onto the front foot and 'into a false sense of security', perhaps.

People talk a lot (online) about teams setting up 4-4-2 or 4-3-3 or whatever else.

But this is a simplification of formations because teams will have (at least) 2/3 formations: they'll have a defensive shape - at it's most extreme, a "parking the bus" shape; they'll have an attacking formation, where players will move up to support; and they'll probably also be drilled in how to organise during transitions between the two. (At least if they are a proverbially "well organised" team.)

The problem is if you're facing a "lesser side", one that's hoping for a draw, etc, they may set up themselves in their defensive / parking the bus shape and... stay there.

And no matter how much playmaking creativity and attacking flair you have, trying to play through two solid banks of four, or even a packed out 5 man defensive midfield, or even 11 men behind the ball, isn't easy.

A team of organised professional footballers playing defensive-mindedly can read and cut out passes or pre-emptively block off passing options, you end up passing sideways in midfield, now what?

Possession-based / tika taka says take your passing between yourselves to such a crazy level it wears them down and pulls them apart, counter-attacking philosophy is more like, screw it, we'll not try and penetrate their defensive shape, we'll force them to come out of it by encouraging them to come forward, transitioning into an attacking shape.

I wouldn't say you want to encourage them "taking shots on goal" tbh, but you get them attacking. Now the wing back or full back is up in your half acting like a winger on the overlap, instead of in defensive position, now the midfielders with part forward/part backward looking responsibilities are concentrating on the attacking side of their game... If you snap a (long) ball forward at this point you've got 4, 5 of their players "out of the game" almost. Instead of playing through a densely packed almost-full-team you have tons of space for your creative operators or box-to-box types to slice clever balls through or dribble through.

Likewise, if you cut out their attempt to play the striker through in midfield, the striker's just made his run, there's no way he's getting back to help with aerial clearances in his own box any time soon.

So by catching them during their attacking or transitional phases you have more space and time, and they are weaker and less equipped to defend you. If they're attacking they are lighter in manpower; if it's a transition they will be relatively disorganised, higher chance of panic/mistakes/loss of team coordination (e.g. that one guy caught out playing everyone onside instead of keeping a perfect line)).
