Blackburn produced one of the shocks of the season to defeat the champions.
“We never expected that,” Ferguson said of the defeat. “We lost two terrible goals in the game and you can’t do that when you are playing a side that’s fighting for their lives. We missed the experience of Michael Carrick and Ryan Giggs in midfield, but having said that when we got back to 2-2 I was certain we would win. Valencia had a great game in the second half but we couldn’t finish them off.”
