"Valencia plays only one way and that's in his role on the right," explained Kanchelskis. "He does not go through the middle and is perhaps not the best dribbler but he's still anyway a main part of Manchester United. He's a really interesting player whose game is important for the team."
The Ukrainian has fond memories of scoring three times in a famous 5-0 thrashing of City in a derby encounter at Old Trafford back in 1994.
"If I have to pick a favourite game, that was it," he continued. "A derby and a hat-trick, my first hat-trick, and it's a great game that I remember."
"I think United are stronger and are playing much better [than last season]. So it's Manchester United to win - definitely to win."
