Four takeaways from Man Utd's defeat to Bayern Munich

Manchester United's Champions League campaign got off to a hectic start as they fell 4-3 to Bayern Munich in Germany.

While the scoreline suggests a narrow affair, United struggled to keep up with Bayern and had a late double from Casemiro to thank for making the scoreline appear more favourable. The pressure has ramped up for manager Erik ten Hag.

Here are four things we learned from United's defeat.

There's no point piling on Andre Onana. The goalkeeper has already admitted he was at fault for Bayern's opening goal and accepted he has not been good enough since making his move to United this summer.

It's an admirable stance but you can't ignore the facts. 14 goals conceded from six games which have seen several shaky moments is simply not good enough and fans may have to be patient before they see the best from Onana.

It brings back memories to David de Gea's early months at Old Trafford. The Spaniard was poor — arguably worse than Onana — but eventually found his footing and became one of the best goalkeepers on the planet.

United fans have been here before but it's time to persevere. De Gea's resurgence is an excellent example of what can happen if a goalkeeper is allowed time to settle in.

One of the earliest issues identified this season was United's midfield imbalance. The signing of Mason Mount clearly didn't yield the early results Ten Hag was expecting but this performance made it clear that the former Chelsea man is not the only player at fault.

Casemiro may have scored twice but his late double only served to paper over the cracks of what was an otherwise frustrating showing from the 31-year-old, who simply couldn't match the athleticism on show in Bayern's midfield.
