Bayern's dressing room verdict on Man Utd will be a major cause for concern for Erik ten Hag

Bayern Munich dominated their Champions League opener against Manchester United but somehow only ended up winning the match 4-3.

They held on to secure all three points but several Bayern players were critical of their performance.

"Thankfully we were able to hold on to the lead. Overall, a really good start to the campaign against a tough side in Man United."

"We were good going forward, but have to stop making so many mistakes," added Leroy Sane.

"There was just too much of that. It was definitely a spectacle for the fans, but we needed to calm the game down and do better on the counter-attack. We were 2-0 up. That's when we have to take control of the game, especially when we win back the ball; then we have to find the right man."

Konrad Laimer echoed Sane's comments, adding: "It was a wild game. There were phases when we could have controlled the game better. We had chances to make the win safe, but we let the opposition back into it. The important thing is starting with three points.

"We know we can and have to improve. If we win in the end, it's good."

Laimer's belief that Bayern have room for improvement will be a concern for Erik ten Hag, who saw his side outplayed for much of the match.

United face Bayern in the reverse fixture at Old Trafford on December 12.
