Man Utd boss Erik ten Hag has three players to blame after Bayern Munich Champions League defeat

Things started well enough. United were positive in the early stages and, had it not been for Bayern defender Alphonso Davies, could even have gone ahead.

The Canada international was alert to prevent Facundo Pellistri from tapping in, with Christian Eriksen then seeing his shot saved.

It is the story of United's season so far, however, that going close soon brings catastrophe.

And for Andre Onana it was certainly a night to forget.

Big things were expected of the Cameroon international when he touched down from Serie A giants Inter Milan back in the summer transfer window as an A-list replacement for David De Gea.

United never had any issues with De Gea's shot-stopping ability. Instead, they felt they needed a goalkeeper who could play out from the back.

But while it's still too early to judge Onana, it already looks to be a disastrous signing. Whisper it quietly but De Gea is still out of work...

The Spaniard's successor was at fault for Bayern's opener, allowing a straightforward shot from Leroy Sane to squirm under his body.

Just four minutes after the goal from the former Manchester City star and the match was suddenly gone.

Bayern doubled their lead, with Serge Gnabry striking into the bottom corner after some sensational work from Jamal Musiala.

Diogo Dalot and Lisandro Martinez didn't do enough. Victor Lindelof, however, seemed to switch off at the defining moment - reacting to developments at a snail's pace.

The Sweden international is a worry. He's been at United for six years now but just never really convinces. The sooner Raphael Varane returns, the better.

Onana is problem No 1. Lindelof, however, isn't too far behind and the more often he plays the more vulnerable his team look.

And then there's Casemiro, too, with the Brazil star a shadow of the player that marshalled the United midfield last season - despite scoring twice.

Just a few months ago the Samba star was being hailed as a magnificent signing, a true game-changer. He took his goals well in the second half - but that's not what he's in the team for.

Most of the game, barring the final stages, the match seemed to pass Casemiro by. Leon Goretzka and Joshua Kimmich were both in a league of their own.

Perhaps there's a reason Real Madrid were happy to sell their midfield gladiator last summer. When you look at how their current central players are faring, Casemiro isn't missed.

United did, of course, get on the scoresheet with Rasmus Hojlund and Casemiro both on target,.

Certainly, Hojlund's strike early in the second half was one of the biggest positives of the night.

Hojlund dreamed of playing for United, scoring for United and playing in the Champions League with the club as well.

He can now cross all three things off his bucket list.

Bayern were only nervy for a short few minutes, however. Not long after Hojlund's goal, a penalty was given following a handball from Christian Eriksen. The Denmark playmaker was unlucky given the ball was blasted straight at him but UEFA rules are far stricter than those in the Premier League.

Harry Kane, rather typically, did the rest - with Mathys Tel netting late on either side of goals from Casemiro.

United won't have too long to dwell on the loss. They're next in action against Burnley on Saturday in a match they cannot afford to drop points in.

Onana, Lindelof and Casemiro must all step up if they're yet to finally get their season kickstarted.
