United looked off the pace at the start of the game, with the Swiss side eying an upset. However, the three-time European champions gradually grew into the game and thanks to two goals from midfielder Paul Pogba, as well as a deft finish from Anthony Martial, United left the Stade de Suisse with all three points.
So here is what we have learned from a win that has taken Manchester United to the top of Group H.
3. Paul Pogba Plays Better When Given More Responsibility
A truly outstanding performance by Paul Pogba. The French World Cup winner was inspirational as United captain, and his first goal was a bolt from the blue which rocketed into the top left corner. He dispatched his penalty with ease, and also assisted Anthony Martial for United's third goal.
This game may prove that when Pogba is given greater responsibility - whether that be wearing the arm-band or being the focal point in the midfield - Pogba can step up to the mark.
2. Kevin Mbabu is a Star in the Making
Why on Earth did Newcastle United let Kevin Mbabu leave the club? The Swiss full-back played just three matches for the Magpies before being sold to Young Boys. Since then he has been a stand-out player for a Young Boys side which won the league at a canter last season.
Although Mbabu was on the losing side against Man Utd, he was one of the best players on the pitch. He's blessed with pace, but also whips a deadly cross into the box. If he can keep on putting in the kind of performances he did against United, then he could easily find himself at one of Europe's biggest clubs.
1. Don't Believe the Hype About Artificial Pitches
If you had been following any of the pre-match talk about Manchester United playing on an artificial pitch against Young Boys, you would have thought they were playing on jelly as opposed to plastic grass, as was the manner of the coverage.
In the end, the unusual pitch played a minimal role. The side which were not used to playing on the artificial pitch won comfortably, and there were not legions of injuries, as some had predicted.
Ultimately, the pitch made little difference to the final result.
