Manchester United
David de Gea 9 Magnificent double save shortly before half-time and a reaction stop late on were every bit as crucial as Van Persie’s hat-trick
Rafael da Silva 7 Surged upfield repeatedly, even popping up in the opposition goalmouth, and was unusually secure at the back
Phil Jones 7 Unsettled early on by Campbell’s pace but responded well even if his blood-and-thunder style kept fans on the edge of their seats
Rio Ferdinand 7 Calm on the ball but his fading authority meantOlympiakos always had chances to score the crucial away goal
Patrice Evra 6 Almost scored from a Van Persie corner but struggled defensively and a yellow card means he will miss the quarter-final first leg
Michael Carrick 7 Booked early on but kept things simple and clearly benefited from having Giggs alongside him to share the creative burden
Ryan Giggs 9 Injected badly needed class and vision into United’s midfield and his ball for Van Persie’s penalty was majestic
Antonio Valencia 6 Recovered from early black eye to charge down the right but as so often this season the Ecuadorian’s final ball was disappointing
Wayne Rooney 9 Stood up when it mattered most. Hit the post, created Van Persie’s second goal, won tackles and was involved in everythingMan of the match
Danny Welbeck 8 Runs in behind gave United extra zest and created pockets of space in which Rooney and Van Persie were able to thrive
Robin van Persie 8 Won and scored a penalty, tapped in a second and completed a hat-trick with a free-kick. Maybe he wants to stay after all?
Olympiakos
Roberto 5 Flapped a couple of times and good saves from Rooney and Evra were spoilt when he failed to react to Van Persie’s free-kick
Leandro Salino 4 Isolated in defence and impotent in attack. Produced little of note until he was booked for kicking the ball away and substituted
Kostas Manolas 5 Booked five minutes in for clipping Welbeck’s heels and was generally given the runaround by United’s front men
Iván Marcano 5 Failed to get close to Van Persie until he was booked at the death for remonstrating with the Dutchman as he lay injured on the floor
José Holebas 6 Drove forward to set up an early chance but his silly challenge gave away the penalty and his threat diminished
Delvin N’Dinga 6 Kept going in central midfield but struggled to stop Carrick and Giggs feeding United’s strikers and shooting was woeful
Giannis Maniatis 6 The Olympiakos captain battled on manfully and kept cajoling his team but failed to exert any great influence
Hernan Peréz 6 Tested United’s defence with his late surges into the box but was withdrawn before the hour to make way for a striker
Alejandro Domínguez 8 Heartbeat of the Greek side, his clever promptings meant United could never settle completely. Unlucky not to score
David Fuster 7 The Spanish midfielder was good on the ball and had a couple of decent efforts on goal but will curse De Gea’s brilliance
Joel Campbell 8 Quick, tricky and with an eye for a pass, the Arsenal loanee was a constant menace but faded in the second half
