Sir Alex Ferguson on the second leg ...
United only needed a tie to go through in 2004. This time, it will probably need a win after last week's 2-2 draw in Manchester.
United manager Sir Alex Ferguson expects to start Rio Ferdinand, whose return should boost the United defense that has looked very shaky in the last month. Ferdinand has been suffering from a groin injury.
United looked bad on both Porto goals -- by Cristian Rodriguez in the fourth minute and Mariano with one minute to play.
"We only have ourselves to blame," Ferguson said of the tying goal. "It just exemplified the fragile nature of our defending at the moment."
Porto -- 1-Helton; 2-Bruno Alves, 14-Rolando, 21-Sapunaru, 28-Cissokho; 8-Lucho Gonzalez, 16-Raul Meireles, 25-Fernando; 9-Lisandro Lopez, 10-Rodriguez, 12-Hulk
Manchester United -- 1-van der Sar; 22-O'Shea, 5-Ferdinand, 15-Vidic, 3-Evra; 24-Fletcher, 16-Carrick, 18-Scholes; 7-Cristiano Ronaldo, 10-Rooney, 9-Berbatov.
