United started the contest in perfect fashion their star man Cristiano Ronaldo on the end of a diagonal ball assisted nicely by Bruno Fernandes. The goal charged the game into life with Young Boys always a dangerous outfit under David Wagner.
Both teams continued to battle each other asking the relevant questions both attackingly and defensively. United themselves dangerous on the counter attack with Ronaldo and Fernandes. But the game took a massive twist as Aaron Wan Bissaka was shown a straight red card having dangerously followed through on Christopher Martins Pereira's foot as he overstretched.
Young Boys grew into the game looking very lively and would grab the equaliser courtesy a ball in for the right for Moumi Ngamaleu to pop in from close range, the ball flicked in beating David De Gea giving him no chance.
Although United fought as much as they could Young Boys took advantage of their home pressure getting a rare win over the Red Devils. This time a goal right on stoppage time to break the ice, a back pass by Jesse Lingard gifting the Switzerland side the three points Theoson Siebatcheu stroking in to the home fans jubilation.
After the 2-1 loss, the United boss spoke to the press and was gutted, starting this years Champions League campaign with a last minute loss.
"I thought we could have done better ourselves first half with 11 men. But we always knew that they are a high intensity, athletic, energetic outfit and I thought we started the game ok, but didn't get the second goal that would have killed the game off. In the second half we didn't have much of the ball, but felt in control, they didn't create many chances. I was very pleased it could have been a well earnt point."
On the red card which caused the Red Devils several problems. But Solskjaer knows it was justified, a lack of discipline potentially the factor:
"I can understand why he gave it, Aaron takes a touch, goes too far, its never a dangerous tackle as it hits him on the front of his foot. We have seen bad injuries, Harvey Elliot being an example, it was never a reckless tackle or malicious. But a little bit of experience having the ball, the boy wasn't going to be injured anyway. Discipline is a huge part of the game and Aaron is normally a good tackler one of the best in the world."
He knows Cristiano Ronaldo has a very important role to play within the club on his return:
"You can never be surprised by the man, he pounced on the mistake, he is exceptional but we have to look after him aswell."
