Both Wigan and Bolton have little to play for having retained their Premier League status for another season with last weekends results.
"People are talking about Wigan's integrity but no one has even mentioned Bolton," Fergie has said.
"All we've seen is Wigan players saying how they'll beat us. Fine, I've no problem with that.
"Then you hear about Bolton players out all week celebrating. Both teams are safe but one is all keyed up to play Manchester United and the other one is celebrating.
"The only thing that gives me confidence about Bolton is the manager and assistant manager."
