United were controversially knocked out at the hands of Real Madrid last week and, while Ferguson is still frustrated by the officiating in the tie, he wishes Los Blancos well, when they face Galatasaray in the last eight.
"I hope Real Madrid do well, but they cannot get a Turkish ref, that's for sure," said Ferguson. "They have a chance but there are four good teams in there.
"Dortmund could be a dark horse, Bayern are strong, Barcelona's performance [against AC Milan] was outstanding and Real.
"They should get through to the semi-finals - and they would be good ones."
