Arsenal's hopes of wiping out a single-goal deficit from the first leg were all over inside 11 minutes as United struck twice to silence an expectant crowd inside the Emirates. Ji-Sung Park pounced on Kieran Gibbs' slip for a close-range finish after eight minutes, while Cristiano Ronaldo fired a 40-yard free-kick past startled keeper Manuel Almunia three minutes later.It left Arsenal's plans, plus Wenger's bold promise of a "magnificent" performance from his players, in tatters as they were simply unable to cope with the power, pace and energy produced by Sir Alex Ferguson's side.
Ronaldo's second goal of the game after 61 minutes summed up their display in the space of a few devastating seconds. Arsenal were undone from their own corner by a superb sweeping move that also involved starring roles for Park and Wayne Rooney before Ronaldo completed the formalities with a flourish.
It rubber-stamped United's passage into a final against Chelsea or Barcelona in Rome later this month - and on this evidence they will take some stopping.
The only blot on United's otherwise perfect night came 16 minutes from time when Darren Fletcher was sent off by referee Roberto Rosetti, who ruled he had fouled Cesc Fabregas as he raced in on goal. Robin van Persie's penalty will not cause United as much pain as Fletcher's suspension for the final.
If United's first-leg performance did not bring the margin of victory it deserved, they were full value for this triumph. (BBC Sport)
