Nemanja Vidic missed a great chance from five yards late in the first half and Dimitar Berbatov had a shot saved. Lisandro Lopez might have scored a dramatic late goal for Porto but his shot was weak and Edwin van Sar saved.It was United's first clean sheet since their FA Cup victory over Fulham on 7 March and it could not have been more timely as United became the first English club to win at Porto in European competition. With Rio Ferdinand restored to the side after a three-game absence there was an increased assuredness to the United backline and in truth Porto failed to create any clear-cut openings until Lisandro's 85th-minute chance.
However, United's failure to score a decisive second goal ensured a nervous final few minutes to the tie as Porto pushed for the equaliser that would have put them through on the away goals rule.
The first 20 minutes of the match must have been close to perfect for United manager Sir Alex Ferguson, who was presiding over his 150th Champions League game. (BBC Sport)
