TBH, you can't really make assumptions, take drastic measures or change your whole strategy due to one bad game.
Us as supporters are very stupid when it comes to this, we want Juve to play 90 mins of great football all matches in a whole season (NEVER IN THE HISTORY OF ANY CLUB). Changes are made when you see group patterns reflected by continuously bad decisions, bad performances which we haven't really seen, except maybe individually in Bentdner and Matri this particular season. Look at Padoin, everyone was talking trash when he came out and played good. It was not his responsibility to change the game anyways.
3-5-2 has been effective, as well as our wingers in other games. Why would you change your whole strategy, formation or seriously talk about signing/getting rid of players for 2 loss matches in 1 1/2 season + Group Stage CL.
The only pattern I see here is overly-confident and overly-dramatic fans. It's fun to read sometimes but ends up being pretty annoying. Get over it, just one game.
Let's focus on the weekend, WITH POSITIVE ENERGY!
