An epic win, but it needs to be the start of something bigger.

I suppose, given how roundly Arsenal had been written off this week in the media and blogosphere, that a win was nigh on inevitable on Saturday. It was a game which confirmed something evident about Arsene's Arsenal in the last few seasons: they can beat any team in Europe in a one-off match.

Things went our way in the game which haven't in other matches recently. Despite cutting open our defence on several occasions early on, Carrick and Rooney, surprisingly given his propensity to score against us, both missed the target when presented with fairly decent chances.

We, by contrast, not only showed a willingness to have a punt from long-range, but even managed to score from one. There was definitely a whiff of the Lampard-deflection-goal-machine in evidence for Nasri's first, but that's what you want to see in that situation. Hitting a ball into a crowded penalty box may result in it bouncing pinball style into the net; it's certainly worth a go every now and again.

There was no luck to Nasri's second effort though. The goal was just about a good a one as you'll see. Too often wonder goals are thought to be those like Bentley's against us - a lucky, if spectacular, hit and hope. To work the ball in the way we did before the goal was superb, and Nasri's finish was emphatic.

The boy is, clearly, pretty good. He may not have the box of tricks that Hleb had when it comes to dribbling. But he works hard, can beat players, can pass the ball to the level required in the side, and isn't afraid to have a shot. That's 4 goals he's scored now in less than 3 months. Hleb barely managed over 10 in 3 years. Ultimately, I think Sammy has that one quality Hleb lacked - bottle.

Samir's goal was followed by possibly the defining moment of the match. Park Ji-Sung floated a ball into the box, and Ronaldo volleyed wide from inside the 6-yard box. If the ball had gone in, I would have bet on United getting at least a point from the match. As it was, the miss seemed to emphasise it wouldn't be United's day.

Not that Howard Webb wasn't trying to help them as much as he could. A series of bizarre decisions in United's favour was capped by him turning down our penalty appeal when Nasri was hauled over in the area. It wasn't a huge tug, but it was enough, and if we'd gone 3 up at that stage, the remaining twenty minutes would have been a lot more comfortable.

As it was, we had to endure a series of rather meandering United attacks, capped by subsitute Rafael's superb volley to bring United back into the game with 6 minutes of injury time left to play.

Yet, we held out and deserved the points.

A lot of people have talked about how thrilling the game was, and I would say it was one of the best games I've ever seen.

What to make of it all is harder to say.

We played the much maligned 4-5-1, and this seemed to get the best out of Diaby and Denilson. Diaby marauded around to great effect in an attacking central midfield role without, perhaps, creating as much of a threat as he could have done. Denilson stroked the ball around well, and kept things ticking over, without really presenting the type of defensive bite we still need in the middle of the park.

Bendtner worked hard, and kept Ferdinand and Vidic on the back foot for most of the game; certainly no mean feat. His profligacy probably stemmed from the fact this was his first start in a game of this magnitude. He will get better.

The defence also seemed to work. Silvestre and Gallas would now appear to be our first choice CB pairing and it's hard to argue with that given Toure's disastrous recent drop in form. Silvestre seems to have improved the defence with his height and aerial expertise, showing just how weak we were in that department before.

Almunia made some excellent saves, yet still doesn't command his area, and his distribution can be erratic. His injury, the result of a very brave attempt to grab the ball from Carrick's foot, was the result of him spilling the ball from one of the few times he came out to try and claim the ball from a cross or corner.

So what has the game really taught us? That this team can beat the very best put in front of it; that we may have found a new CB partnership; that we would still be improved by a greater deal of bite in midfield; that Diaby has to play in the middle; that Nasri might just be a really great signing.

But does it show that the team are title contenders again? I'm not sure. If we haven't lost any more games before January, and remain within 3-6 points of the top, then maybe. But we need signings in the window even if that is the case, if we are going to really build on yesterday's result. In any case, it's nice to be proud of the team, and for Arsene to get some praise.
