A last-gasp strike by Italian striker Luca Toni handed Bayern a 2-1 win.
“Where should we go from here?,” said Rangnick after the game. “Obviously we’re gutted, as a point here would have been totally deserved.
“I can’t say a word of criticism against my team. It was a very intense and physical game.
“We were really strong at the start of the second half, we opened the scoring and could even have made it two.
“Then we conceded the equaliser, but Salihovic had the match on his boot in the 87th minute.
“Naturally, letting in the winner after 91 minutes is devastating, but I’m certain we’ll ultimately benefit from this match. It’s been a good experience.”
