Fred the Red and Moonchester went head-to-head in a pre-derby meeting at Manchester's Chill Factore.
Tipped to be one of the matches of the season, the two mascots compared skiing and snowboarding techniques and challenged each other to a snowball fight, refereed by Chill Factore mascot ‘Chille the Snowboy'.
The mascot meeting took place ahead of a special derby-themed ski session at Chill Factore on Tuesday 8 February, with skiers and boarders invited to take part in a challenge to see which club has the "best" footfall fans in Manchester.
Manchester United and Manchester City supporters, young and old, are invited to wear their team colours on the main slope from 4pm to 5pm. As well as seeing which team has the most shirts on the snow, up to ten supporters from each club will be hand-picked by the instructors to take part in a supporters' downhill derby with the fastest team to complete the challenge crowned the winners.
Morwenna Angove, chief executive at Chill Factore, says: "The Manchester derby is a key date in the city's calendar. We know that many of our guests will be watching the game at the weekend and we wanted to tap into the friendly rivalry between the two clubs.
"Tomorrow's event promises to be great fun for children and adults alike and the results of the supporters' downhill derby may well give the winning team some early bragging rights ahead of the big match on Saturday."
