Sylvain Distin hopes Manchester United's crushing derby defeat is still fresh in their minds as Everton prepare to face the reigning Barclays Premier League champions at Goodison Park this weekend.
The 33-year-old Toffees defender knows a thing or two about the impact such games can have on a player's mindset, having spent five years as a Manchester City player, making 178 appearances for his former club.
The fact that United were condemned to such an emphatic defeat at Old Trafford last Sunday, the Frenchman wants his teammates to capitalise on any psychological damage and potential weakness, and take the three points.
"They must have a lot of questions in their mind that's for sure," Distin told the Liverpool Echo. "When you lose a game like that, especially a derby 6-1, and City make history it must be one of the worst days for United's players and staff in a long time.
"So definitely they're going to doubt and it's up to us to try and make sure they doubt right from the start."
Distin knows that Everton will face a tough test against Sir Alex Ferguson's wounded side, and expects the Red Devils boss will have used the City loss to fire his players up.
"Knowing Alex Ferguson, United will come here having had a tough time," he added. "They will want to prove it was a one-off mistake, but it'll be up to us to make them doubt right from the beginning and then we'll have a chance.
"We have a decent record against them at Goodison. Yes we lost against Chelsea but we showed some character and we'll start the game quite positive."
