Inter blew a 2-0 lead to lose 3-2 in Germany.
Conte barked: “We have too limited a squad to face both Serie A and Champions League football this season. I mean limited both in terms of numbers and quality.
“Some players have to be on the field constantly and in the long run, you do pay for that. I am furious, because this cancels out all the good work."
He continued: "I am not asking the club for anything, these are the players and we go into battle with these players. The club will make its evaluations, I am just saying all of us got it badly wrong when planning for this season.
“We are in an emergency situation with only three players injured, whereas other teams have injuries and don't even notice. We notice.
“We are talking about a group of players who, apart from Godin, haven't won anything. It's difficult then to deal with a tough situation.
“Who do I call on? Nicolò Barella, who we signed from Cagliari? Or Stefano Sensi, who arrived from Sassuolo? I will always thank the players for giving their heart and soul, and I know that I am asking for the kind of strain that some find it difficult to deal with.
“We can't let our current position in the table disguise the problems that are there."
