Manchester United
Edwin van der Sar Conceded twice but kept Porto at bay at times as he denied Lopez twice and also kept out Rodriguez, Meireles and Cissokho 7
John O'Shea Defensively poor as he struggled to contain the lively Rodriguez and was fortunate that a wayward back-pass was not punished 5
Jonny Evans Error gave Porto their opener and was in keeping with a nervous start. Did his best to recover. Replaced after picking up injury 5
Nemanja Vidic More assured than Evans on a testing evening for United's defence. Came close to scoring with thumping header 6
Patrice Evra Offered forward thrust on the left but had a difficult opponent in Lopez and will not look forward to facing him again 6
Darren Fletcher Used the ball better than any other United midfielder but influence waned when he was pushed wide in the second half 6
Michael Carrick Showed usual cool head with the ball yet seemed unable to stamp his authority on the game as Ferguson would have wished 6
Paul Scholes Passing was a little wayward at times and, one burst in the area apart, this was an underwhelming night. Replaced by Tevez 6
Cristiano Ronaldo Gave away possession in the lead-up to Porto's first goal and was disappointing. Lots of flicks but little end product 6
Wayne Rooney United's best outfield player. Took his goal brilliantly, unlucky with an audacious lob and set up Tevez's equaliser 8
Ji-Sung Park Full of energy and stung Helton's hands from 20 yards but lacked real threat and was predictably withdrawn for Giggs 5
Substitutes: Ryan Giggs 6 (for Park 58), Carlos Tevez 7 (for Scholes 72), Gary Neville 6 (for Evans 72)
Porto
Helton Unsure with kicking but blameless for the goals. Made excellent saves to thwart Rooney and Vidic in space of 60 seconds 7
Cristian Sapunaru Aggressive challenge on Ronaldo set the tone. Kept Park quiet even if his tackling was occasionally over zealous 6
Rolando Came under more pressure when Ronaldo joined Rooney in attack yet the defender rarely looked flustered 6
Bruno Alves A miserable night.His suicidal back-pass allowed Rooney to equalise for United and he was later booked for handball 4
Aly Cissokho Confident enough to break forward and test Van der Sar from distance. He was comfortable on the left side of defence 7
Lucho Intelligent with the ball and often at the hub of Porto's better moves with his probing passing as he sought to link up play 7
Fernando Deployed in the holding role, the Brazilian broke up play well and also demonstrated a willingness to break from deep positions 6
Raul Meireles Neat and tidy and showed some dexterous touches but was unable to the dominate midfield and was later substituted 6
Lisandro Left Evans for dead in third minute before stinging drive was tipped over and remained a threat. Set up the second goal 7
Hulk The focal point in the Porto attack but the least effective of their three forwards. Troubled Vidic earlier with his trickery 6
Cristian Rodriguez As luminous as his green boots. The Uruguayan was a constant menace to the United defence and fully deserved excellent goal 8
Substitutes: Mariano 7 (for Rodriguez 79), Costa 6 (for Meireles 79), Madrid (for Costa 90)
