"The great thing for Wes Brown is that he has remained fit this year," said Ferguson.
"Last season, he had a terrible run of injuries. But the previous year, he made the most appearances and played in the final in Moscow.
"When he is fit and we bring him in there is no better defender in the country. He is a real true defender.
"I have no worries about Sunday in terms of Brown and Evans - absolutely no worries at all."
