Jose Mourinho decided against signing autographs after a fan hurled a snowball at him in Bodo, a town in Norway.
His Roma side play against the Norwegian outfit in the Europa Conference League tonight and Mourinho was greeted by some of the supporters the day before the game.
He was walking off to a group of fans who had gathered at a fence near where Roma's base was. Even in the freezing cold, Mourinho was fully preparing to take pictures and sign items for those present who shouted his name.
But then one fan ended up spoiling it for everyone when he hurled a snowball in the direction of the former Chelsea, Inter Milan and Real Madrid boss.
Although the snowball just missed him, Mourinho, understandably furious, then turned away and did not sign any autographs.
Instead, he got back on the bus and on his way.
At the end of the clip doing the rounds online, you see a member of security stuff gesture to the fans - clearly not happy with the antics.
There's been an overwhelming negative reaction to the scenes on social media, while some joked that Ole Gunnar Solskjaer threw the snow.
