It really has been a rout and the scoreline does not flatter United in the slightest.

It's exhibition stuff by United as they look to score a fourth goal which would really put the icing on the cake.

It has been almost embarrassingly one-sided at times as United have barely got out of first gear for long spells.

Nani and Valencia set up Gibson who has a great chance to make it 4-0. However, he lifts his head just as he is about to shoot and lifts his effort way over the bar.

The anti-Glazer chants start up again as United cruise through the closing minutes.

Elsewhere, Real Madrid look set to crash out at the last-16 stage once again. Lyon have equalised on the night so Real need to score twice in the closing stages to progress.

As usual, United appear to be hitting top form at exactly the right time. A third successive Champions League final does not appear to be beyond them on this showing.

It's almost a dream return for Beckham as he lashes a shot towards goal. Unfortunately it's straight at van der Sar who is able to beat the effort away.

Valencia's shot is charged down by Ambrosini as United look for a fourth goal.

Van der Sar gets down well to save Ronaldinho's flick as the match meanders to a conclusion.

Nani is lucky not to be booked after falling over under Massimo Ambrosini's challenge.

Milan would struggle to finish in the top half of the Premier League on this display.

Milan's display is really showing the depths to which Italian football has sunk in recent years. Maybe Inter can upheld Serie A's tradition against Chelsea next week?

It is becoming a stroll for Ferguson's men now as Milan try, without success, to probe the home defence.

The match is in danger of being a damp squib from now on although Huntelaar heads another presentable chance over the bar.

The United fans start, now the match is won, to chant their anti-Glazer songs.

Valencia is keen to get in on the act, blasting a low drive wide from a very tight angle when team-mates were better placed in the penalty area.

That really is game over. It will be a damage-limitation exercise by Milan now.

United break free just before the half-time whistle and, as Milan back off again, Fletcher's drive flies narrowly wide.

Milan finish the half with a long spell of possession but they're unable to create anything of note. Rooney's goal seems to have ended this tie as a contest.

Ronaldinho is spotted tracking back into his own half as he desperately tries to get a rare touch of the ball.

There's a gulf in class between the two teams with United in cruise-control at the moment.

United remain in complete control with Milan seemingly uncertain what to do next.

Neville finds more space down the right, but this time his cross sails harmlessly out of play.

Apart from one early chance, Ronaldinho has been very quiet. He drops back into midfield in an attempt to win some possession for his side.

Milan are bizarrely letting Neville have acres of room to do as he wants. This time the veteran defender has time to whip in another cross that is eventually dealt with.

The referee has a word with Paul Scholes after a trademark rash challenge by the veteran midfielder on Mathieu Flamini.

Silva, who has started very well, tidies up at the back as Ji-Sung Park tries to burst free.

United have this tie by the scruff of the neck. There doesn't seem to be any way back for Leonardo's side at this stage.

Rooney is crowded out after almost being set free by Darren Fletcher's astute pass.

Antonio Valencia's trickery wins a corner and from it Silva heads the ball away from danger.

Patrice Evra sends in a poor cross that drifts behind the Milan goal.

Milan go close to pulling one goal back as Pirlo rifles a shot through a crowd of players that van der Sar eventually gathers at the second attempt.

Having grabbed the goal, United now seem happy to sit back and let Milan come at them.

After a blistering opening 15 minutes, the match finally starts to settle down.

That should really be that. Milan need to score three goals now.

Those two moves should serve as a warning to United as Milan are certainly capable of winning this tie.

Milan create another great opening. Thiago Silva's long ball forward finds Klaas-Jan Huntelaar who is onside. However, the Dutchman's first touch is poor and van der Sar is able to claim the ball. Huntelaar should have done much better with that one.

Milan almost take the lead. Andrea Pirlo's free-kick is inadvertently headed on by Nani to Ronaldinho whose instinctive header is only just off target with Edwin van der Sar rooted to the spot.

Milan are struggling to get a foothold in the game. United's pace seems to be too much for them in the opening salvos.

Now Gary Neville gets involved in the action and almost finds the target with a looping effort that drifts inches over the bar.

Rooney tries his luck from distance again but this one is sliced hopelessly wide of the target.

The Rossoneri have hardly been out of their own half as United's bright start continues.

It's almost 1-0 to United as Rooney turns adroitly, spins and sends a shot from the edge of the area just wide. Good start by United.

Nani is crowded out as a lively early United attack breaks down.
