Fan blogger Ollie Hirst looks ahead to Saturday's game...
Not even the most ardent of Hammers fans saw Sunday's result coming - not least the unfortunate bloke who had the result and scorers tattooed onto his backside. It had been eight years since we got a result there and what a win it was. It was the classic away performance; we defended resolutely, attacked with flair and purpose and ultimately, took our chances.
It was unexpected because Arsenal are one of the title favourites, because of what happened to us in Europe and perhaps, also because we had a player younger than the £2 coin holding our midfield together. Reece Oxford was outstanding, though, as was Dimitri Payet (among others) and the problem now is that uncertainty soon turns to expectation.
At home to Leicester City, who are many people's pick to be down there come the end of the season, we will be expected to build on Sunday and win. I guarantee that when each one of us first looked at this season's fixture list we all thought: two games, three points.
Now, heading into our clash with the Foxes having already reached that tally, we're hungry for more and quite rightly, too. In many ways, though, Leicester will be a tougher test than Arsenal.
The way we set up at the Emirates was designed first to absorb pressure and only then to punish the hosts whenever the opportunity arose. At home, the impetus will be on us to attack and perhaps things won't be so compact at the other end as a result - with Leicester looking to be as devastating as we were on the break.
They'll be full of confidence, having stunned Sunderland with a 4-2 win at the King Power which, in all honesty, flattered Dick Advocaat's side and are clearly still buoyed by the form that kept them up against the odds last season.
This is not me trying to get my excuses in early or anything - quite the contrary. I'm still expecting the three points I promised myself upon that first glance at the fixtures two months ago. But nothing's a given even after last weekend's success and it will be a different game entirely.
Still, the remit this year is clearly to entertain, especially at home. It's why we appointed Slaven Bilic ahead of others and why we were quick to make Payet, who created more chances than any other player in Europe's top leagues last term, a West Ham player. We will be expected to attack.
Football is as much mental as it is physical and there's no question there's less pressure involved in a trip to the Emirates than there is in your first home game of the season against favourable opponents.
But we've plenty of reason to be confident and hopefully the fact we already got those three points on Sunday will allow the players to be a bit more relaxed. There's also a bit of a buzz around the place at the minute and that should translate when the lads emerge from the tunnel on Saturday.
Fingers crossed we'll have Diafra Sakho available and Mauro Zarate is in the form of his life at present, so we've every reason to believe it'll be six points from six by the time we tune into Match of the Day.
