The United fans are in Spain for the club’s Europa League quarter-final against Sevilla.
However, for one fan it got off to the worst start as they took a tumble from their seat.
On his way down he fell into the fans standing in front of him on the lower rows.
By doing this, he caused them to also fall down but luckily for them they appeared to be fine.
The moment was caught on camera and broadcast, which led to supporters sharing their concern on social media.
One fan tweeted: “Hope the MUFC supporter who we saw fall there is ok? 😬”
A second speculated: “Actually, rewatching it, it looks like he may have fainted.”
A third commented: “Wonder if he’s ok?”
Things did not start well for Man United on the pitch either as Youssef En-Nesyr gave Sevilla the lead in the 8th minute.
