Keep Rooney quiet and Gunners can win
Arsenal have been brilliant so far this season. They've done everything that's been asked of them and I really believe they can win at Old Trafford.
Manchester United haven't been quite so clever this year. They allowed Birmingham too many chances at Old Trafford and then they had that shocking result at Burnley. They beat Wigan 5-0 last weekend but I thought the score was a bit harsh; Wigan had chances to score and United had a mad rush of goals at the end.
Arsenal: is a big win on the cards?
United will get stronger when Edwin van der Sar returns and they have been nowhere near as solid as they usually are without Rio Ferdinand. For me, he is their main defender and they miss him.
They obviously miss a certain Cristiano Ronaldo too and I don't think they are as strong as they used to be in midfield.
Arsenal might be without Cesc Fabregas but I still think they are a better passing team in midfield right now.
The biggest factor of all is whether Arsenal can stop Wayne Rooney. Thomas Vermaelen hasn't come up against anybody even similar to Rooney yet and there could be a big shock in store for him. A lot will depend on that battle because if Rooney plays well then United have every chance.
He didn't get much help from his fellow forwards at Burnley, but I'm sure the strike partnerships will click. However, it needs to be sooner rather than later because Chelsea have started strongly.
People say there's a long way to go but this is a big game. If Chelsea win on Saturday and United lose, then they will be six points behind already.
In the race
At the moment Arsenal are very much in that title race as well. They've played so well this season and I don't think they got enough credit for last week's win at Parkhead. That was an unbelievable result and it slipped under the radar a little bit.
So far, so good but I do fear for Arsenal when injuries start creeping in later in the season.
But right now they couldn't be playing better and they are full of confidence so this is the perfect time to go to Old Trafford.
At home, Arsenal would be expected to take it to United, but at Old Trafford Arsenal can counter-attack - and they are doing that much better this season.
They are breaking with pace and getting people in the box - and I think they will definitely get a result.
