How right of Jonathan Northcroft to highlight Anderson's performance. We know Rooney and Ronaldo are the leaders in this team but in two years Anderson will be the star man. This season he has overshadowed both Fabregas (twice) and Gerrard, who are apparently the top midfield men in England.

It is something special to watch the left footed central midfielder, Gerson, Overath, Van Hanagem, Hagi, Rivelino and Davids were all very special to watch. Anderson is one to follow these.

Peter Hogg; point of order: Keane's tackle never ended Haaland's career. Haaland retired because of an injury to his OTHER knee.

AND how can you say this was Utd at it's best "with the exception of Hargreaves, Ronaldo and Tevez". Surely then, this is Utd at 73% strength?

What should have happened to Gallas then? I like him as a player, but I'm sure even he admits that he was lucky the ref didn't see him. Clear red card. This was just another typical Arsenal display when they have a hard game against Utd: petulant. Throwing pizzas? Keown taunting van Nistelrooy?

Nani was naughty taunting Arsenal like that, but at least Fergie had a word with him afterwards and told him to cut it out. This makes a refreshing change from Wenger who never seems to see any of his team's infringements.

Nev, Amsterdam,

Why are Arsenal fans such sore losers? jeez, that wasn't even Man Utd's strongest team and we still routed Arsenal 4-0 and that score could've easily been double that. Arsenal are sounding like Chelsea of last season and blaming everything on injury. Man Utd has injuries as well and we still show up and win matches. Arsenal were outclassed and outplayed by the better team.

Kema, London,

I have to say that I don't watch that much football these days, but I saw yesterdays match. If all matches were that exciitng to watch I would watch more of these over paid ballerinas. Re the showboating of Nani...surely the pitch is a stage to show off what you can do, where else are you going to do it?

Half of these footballers forget that they are there to entertain the thousands of people who support them week in week out which these days is no mean feat in terms of taking a family to see a game in the premiere league!

Nick , Cranbrook, Kent, U.K.

Arsenal can play the illness/injury card if they like, has never washed with any other club, won't wash with Arsenal.

Man Utd simply out played them at their own game, Anderson is only 19 and was superb, had a mention for the Arsenal Fabregas.

Then the second half they seemed to have instruction to injure a Utd player.

And Nicolas Kozeschnik, I fail to see how Wiley was Utd's 12th Man, had be been Arsenal would have definately lost more players, I seem to remember Utd fans complaing about Webb's performance at the Emirates earlier in the season, where so many fouls were not given and on lead to Arsenal managing to scrape an equaliser.

The simple fact about yesterday - Arsenal shots on target = ZERO, simple can't win games it you can get at goal.

Glen Banyard, Ely, UK

I think before Man U or their manager take the high ground on sportsmanship, where was fergie when keane admitted his tackle ended haglands carreer, on purpose? As usual nowhere. Don't give me this was a weak Man U team, this was their best, with the exception of Hargreaves, Ronaldo and Tevez. Do I need to list the 9 arsenal absentees, or the fact that Van Persie has been absent virtually all season. This was no mighty tactical decision by Fergie, the press told him all week that arsenal were seriously depleted. Can't wait to see a fit Van Persie and Adeybayor take on the erratic Ferdinand in April, things could be so very different. Once again Fergie is up to his tricks and attempts to influence the FA, red card gallas for a petulant kick. He will never be regarded in the same class as Matt Busby, a true gentleman of the game, who would never stoop so low

Can't agree more with you Monty, Bermuda. Never seen such an awful performance...

How much longer is Wenger gonna keep using Lehmann? He should be on his way out now, before his blunders shames the club .. again and again!

Maggie May Gunners 4-ever, Selangor, Malaysia

The Old Trafford pitch is a disgrace to football. Sunday league council pitch’s are in better conditions. Alan Wiley was Sir Alex’s 12th man in his many strange decsions all match that went hugely favoruable to United. You could even argue he was a United fan. Justin Hoyte, Armand Traore and Emmanuel Eboue are simply not good enough at this level and Gilberto Silva’s days are numbered as are Jens Lehmanns. Good luck United in the FA Cup but the Premier League Title is coming South to the Emirates – even Ferguson admits that!

Nicolas Kozeschnik, Hertfordshire, England

Is juggling the ball more disrespectful than holding the ball under the goalkeeper's nose after taking it around him to score (Thierry Henry/Chris Kirkland two seasons ago) - you need to get that selective memory sorted Arsene, people are starting to laugh at you.

Stephen Wilson, Plymouth, UK

Agree with star man rating for Anderson .He is simply awesome. If he improves on this showing in the next few years he will be competing for ballon d'Or ! What a talent.

United was very impressive last night but let us not write Arsenal off at this point. Have no doubt that the quality in the Arsenal team will be demonstrated on Wednesday night.

It is very unusual to see Arsenal lose - especially by such a wide margin, the team certainly didn't play with their usual passing flair. Rooney was simply brilliant which bodes well for the national squad. Wayne is well accustomed to the physicality of the English game but Eduardo is only just learning to be more robust, he was the subject of many nasty tackles on Saturday that went without censure. After half time Eduardo's attempt at standing up to the United defence was greeted with a yellow card, incredible that he was reprimanded after merely trying to be aggressive in kind after 45 mins of being kicked about.

What sometimes holds Arsenal back is an inability to be covertly aggressive; the skills of European footballers are overshadowed by the physicality of the English game.

that'll learn 'em

steve, brixton,

Why focus your headline on Rooney, who we're bored of hearing about, when there was a one-off chance to praise the normally obscure Fletcher? The man scored two goals for goodness' sake, give him his due. I'm an Arsenal fan so it's especially bad that we let this guy score twice, but you might as well let him have his time in the spotlight, rather than keep it on the same old usual suspect in Rooney.

H.W.Davies, Ware,

Forget Nani's show. There are a lot of things that the Arsenal players shouldn't have done too. Like Flamini's tackle and Gallas' little piece of 'sportsmanship' one minute later. Or the attack on van Nistelrooy some years ago, or the pizza-gate or, or, or...

James, Thessaloniki, Greece

It shows where the FA Cup is these days.

Come wednesday, Utd will be be behind and Arsenal will be in front, and it will be that way in the EPL as well.

D.Dent, Ipswich,

Monty in Bermuda, what an utterly stupid comment to make.

John, London,

Not sure that I accept that Nani was show-boating. He was facing his own goal and keeping the ball up like that and moving fairly quickly was the only way he could keep the ball when the Arsenal clods were hacking away at him.

Good to see all those empty spaces in E stand towards the end of the game. Safe journey back to London, lads.

David, Poole,

As a paying customer at OT, players like Nani can "show boat all they like" for me. Fabregas will likely do it next week (I will enjoy the same) and Wenger will no doubt see it different; just like he does with everything else that portrays Arsenal in a negative light. Carefull Arsen, if you happen to be looking the other way again you are going to blow the Premiership with your usual petulant behaviour. Shame because you have footballing team with class in abundance.

ManUtd deseves first prize this season.

Judgeing by the display by Hoyte it's little wonder Wenger hasn't got any Englishmen in his team.

Monty, Bermuda,

Nani shouldn't display his skill because it's disrespectful? What's the point of having such a skill if you can't use it where it matters? Or have I missed the point? If a player wants to "showboat" his or her skills on the pitch it may have some reflection on the opposition team's inability to prevent it in the first place....long live showboating, it's one of the few redeeming features of an increasingly ugly game.

a terrible defeat for arsenal

Antoine, Warsaw, Poland

Gallas and Toure's partnership was destablised because they constantly had to cover for their woeful full-backs - Traore and Hoyte. Bacary Sagna and Clichy were really missed. I do not know just what Wenger keeps seeing in Hoyte and Traore. Traore and Hoyte's positional play is so juvenile that both were again exposed in the 5-1 drubbing at White Hart Lane. I notice that Traore can hardly use his right leg - he is very handicapped, defensively. It is also now clear that Gilberto is fast becoming a liablility and Flamini is now the main man. It is also baffling how in 90 minutes our centre-forward - Bendtner could not even manage a shot on goal - terrible!
