Erik ten Hag has warned Manchester United's players they have to "sacrifice" if they are to end their losing run after a third successive defeat.
United lost for the fourth time out of their six games this term to Bayern Munich in their Champions League group stage opener, conceding four goals in the competition for the first time since the 4-0 hammering by Barcelona in 1994.
Bayern prevailed 4-3 but had 10 more attempts at goal than United, who conceded within four minutes after scoring their first and second goals.

Although Andre Onana's clanger sparked a mini collapse from United in the first half, Ten Hag was also furious with the build-up to Leroy Sane's 28th-minute opener as well as Serge Gnabry's strike four minutes later.
"Disappointed and when you score three goals in Munich, at the least you have to take a point and we didn't," Ten Hag lamented. "And you have to look in the mirror because the goals were easy giveaways.
"We were in the first 25 minutes better in the game than Munich and then that goal, it was so easy and it was not only Andre. If you see how easy Sane is going through and that has to do with determination, you don't let players through so easy.
"That is the point - we have to cross the line as an individual and as a team to win games because it started there. That's what I mean, you have to suffer, sacrifice in situations, to give everything and to stop that and only when we get that in are we going to win games.
"Of course, he (Onana) knows he has to stop the ball but the way Sane came through can't be. And the second goal; it's almost similar over the other side. How easy players come
