There's no doubt about, Arsenal's visit to Old Trafford on Saturday is their biggest game of the season thus far. Last time out in Manchester, Laurent Koscienly scored a late equaliser to snatch a draw from the Champions, Manchester City. It didn't go too well last time out at Old Trafford, as they suffered an embarassing 8-2 defeat last season.

Currently lying seven points off top spot, Arsenal desperately need something out of Saturday's game, if they want to continue to dream about a first Premier League title in nine years. They do have a squad to cause United problems, Carzola and Podolski have been off the boil in recent weeks, but a first visit to Old Trafford should give them the hunger to cause a leaky United defence problems. Arsenal showed their attacking abilites against Reading as they scored seven goals, three of which by Theo Walcott. The young Englishman's future is in doubt, but Arsene Wenger is desperate for him to sign a new deal. 

Arsenal do have a side capable of winning the title, their additions in the summer showed their intent, bringing in Santi Carzola and Lukas Podolski. Already adding to their a strong squad, which has recently seen Jack Wilshere return, practically like a new signing. The most disappointing part of the summer was letting Robin Van Persie leave, as the attacking players they'd brought in along with Olivier Giroud would have made them really formidable if they still had Van Persie. In January, Wenger needs money, to buy a striker that can replace Van Persie's goals. Arsenal need to look at Atletico Madrid who've managed to replace top strikers over and over again. Fernando Llorente has been linked to Arsenal recently and he would fantastic buy. Out of favour at Bilbao and on the last year of his contract, Arsenal could push for a bargain. Llorente offers lots to the table for Arsenal, his tall stature, technical skill and deadly finishing make him a nightmare for defenders everywhere. Manchester United fans will tell you of the dangers he has in his locker, as he made United look foolish over two legs in the Europa League.

Futhermore, the defence is still a problem at Arsenal. Shipping five goals against Reading can't be seen as successful and they were second rate at Norwich. Kolo Toure has recently spoken out at his frustaration at being left out at City, with a move to France on the cards. A move from his old employers to sign him may tempt, his presence would surely strengthen the back line. 

Arsenal do have the potential to win the title, it'll be just about getting right at the right time. A win on Saturday, would put them right into contention before they potentially start dropping away. Wenger will be assessing his sides strengths and weaknessess as he looks to add to his squad in January, a new centreback and striker, could be high on the agenda.
