Here's the thing, friends... If we had Lippi, Capello, Mourinho, SAF or any other "world-class" coach, we still would've lost the game.
1- Bayern's squad is better than Juve's by large landslide. We knew this since the beginning of the season. In 1-to-1 battles between players, Conte can do nothing about Ribery taking the better of his best defender Barzagli or Lahm and Muller making Peluso looks like an amatuer.
2- Bayern has virtually won the Bundesliga, rested a lot of important players and had a training session against HSV while we still fight for the scudetto and had a hard battle away from home with one of our fieriest rivals.
3- Despite their total domination, if Bayern didn't get that early lucky goal, ref called an offside for their 2nd goal and gave us a penalty for Lichtsteinter, everybody would be here hailing Conte for masterminding the best tactical approach in history. Small details matter and in our case it went totally wrong.
4- Everybody approved Conte's starting 11 even though you're not really aware who's ready and who's not because only Conte can monitor his players on daily basis.
5- Players had an absolute shocker, Buffon was Valdesish, Pirlo looked like a dead man, Marchisio was non-existant, the entire defense was shaky, Quag/Matri failed to hold up one single ball to start a proper attack. Vuci/Gio didn't improve anything, Pogba too. Conte cannot sub out everybody and it's not smart to make all your subs early on and then have one or two players injured, say 20 minutes from FT.
Not saying that Conte is not making any mistakes, but in this particular game, it's out of Antonio's hand.. For example, Asamoah would've been a better option than Peluso but we would've still lost the game. Reaching the QF and winning the scudetto again is simply amazing and as @Hist mentioned, Managers like Klopp (with his Bundesliga holders) failed to even get out of the group stage in his first CL attempt.
