Bayern were held to a 0-0 draw by Cologne on Saturday.
“You simply have to score at home,” said Schweinsteiger.
“As we say in Bavaria, it’s enough to make you sick – and that’s how it is.
“We had so many chances, but we’ve failed to score.
“We hit the bar, or we hit our own players.
“We were unlucky on occasion, but sometimes we weren’t ruthless or smart enough.
“It’s a bit depressing frankly. It’s a real shame we?ve only taken a point.”
