No they dont.
They focus on keeping shape and not getting dragged out to leave space as happened when Semedo followed Benzema,
Again you say Pique had to close down... he doesnt have to be closer to Semedo there for any reason until that pass in behind is on and that takes around second for Semedo to leave that run on and Pique to cover so virtually impossible anyway.
By far and away the lesser threat is to keep shape and give Benzema a bit more time to get on ball there.
No top team will aim to defend the way Semedo did there and if it happens they are leaving themselves open.
Teams dont defend 'overloads on flanks' through their ful backs follwing players out of defence and asking their CBs to cover the space left and front up to the wide players. No team whatsoever wants to defend like that.
And as I said, shape is dependent on the position on the ball and the opponent's actions. You let the opponent create superiority at will, and you will have all sorts of problems. Main course of action is to stop the progression of an attack near the ball, in close spaces, at the expense of leaving more space in farther areas. The farther an area is the harder it is to be accessed by a player on the ball quickly.
Your strategy is basically reducing your defense to last ditch tackles after the defense is already penetrated. Because you stick to positions without looking at the ball.
The root of your argument is that you think Benzema receiving the ball where he would have is dangerous and needs to be mitigated. Which is flat out dumb. What's he going to do at that spot? Send Vinicius in on the wing? Probably. But Semedo has it covered if he stays + Braithwaite would come to help. Drive and shoot? He never does it, because a) he's too slow and everyone catches up and b) because he prefers to walk into the goal. Pass to Carvajal who is running onto weak foot? Bad play and he'd probably not do it. You can find tonnes of video footage showing you how passive Benzema plays on the left wing once he drops to receive the ball.
Your judgement is bizarre. It's odd how wrong you judge this situation.
You are basing a defensive strategy on things like Benzema not being very good, or not being this or that. It doesn't work that way. The view is systemic. You don't let a pass on that can hurt you in a variety of ways because Benzema is this or that.
Good thing we quadruple marked Carvajal and that player, whoever that filler player is in the box (who's actually the real bait here lol keeping our CBs away from the action), and allowed Benzema, Kross and Vinicius, probably 3 of Madrid's most dangerous players create havoc on that side.
