We can't get too excited about today. The team is better than people think.” United goalkeeper Edwin van der Sar made a top quality diving save to keep out a free kick by Fabio Aurelio in the 15th minute but Liverpool was rewarded for its improved play by taking the lead in the 65th. Torres collected a through ball from Yossi Benayoun and held off Rio Ferdinand before shooting into the roof of the net.
