Bayern Munich defender Daniel van Buyten scored the only goal in the match.
Lacatus said: “I’m a bit disappointed with the result.
“We had hoped to counter attack Bayern a lot more but unfortunately that didn’t happen and we conceded a goal after a quarter of an hour.”
He added: “After that we had to play more aggressively but we couldn’t manage it. In the second half we were better and were a little unlucky with our chances.
“Bayern have a few very good players, who are physically very strong. Unfortunately we have lost our first game at home, but hopefully we will get the points in our next game so that we can still be in Europe at the start of the New Year.”
