If you're just tuning in, Ole Gunner Solskjaer has tasted defeat for the first time as Manchester United boss.
Goals from Presnel Kimpembe and Kylian Mbappe have put them in a very strong position. Pauk Pogba was sent off for the hosts as well.
PSG boss Thomas Tuchel: "Angel di Maria is very competitive. If you tease him, it does not make him weaker.
PSG forward Kylian Mbappe: "People have to stop selling fear and being afraid.
Manchester United midfielder Ander Herrera speaking to BT Sport: "The game was tight until the corner. After the first goal everything changed. The game was under control. The game could have finished 0-0 if they didn't score from the corner. They then played counter-attack because they have very quick players.
"I think we lost some pace [when Antony Martial and Jesse Lingard went off injured in the first half] but won some combination with Alexis Sanchez and Juan Mata. We were pressing OK and they were not feeling good with the ball.
