If our physical problems won't magically disappear in the next couple of days, Flick should really consider to play more defensively. Because without a perfect pressing, Madrid will murder us with through passes on Mbappe and Vinicius.
It's a difficult decision for Flick. He knows his tactic stands and falls with the team's legs, especially against the ball and that's so far our biggest problem this season. The team just runs less. At least Fermin can and will start, but for Rapha this game is too early, even if he gets the green light in the last minute.
Tek is also a huge risk for a red card / penalty against Mbappe, if he needs to run out.
The signs could be better, not gonna lie. At some point, we'll lose a clasico again obviously and this one will be the most unimportant of the season.
