Arsenal's fate is still swinging yet as their possibility of winning either the league title or the Champions league isn't certain yet but I can assure you that these boys are eager for a title this season that was why they flopped and at a time they picked form again so it wouldn't be a surprise if they take home a trophy this season.
Their eagerness to win a title may not still be enough. From the position the club is currently, they can either win the two titles in the competitions they are in, which are the premier league and the Champions league, or win the premier league that they are topping, or loose both competitions and end up winning nothing again this season. Arsenal has really gone too long without any major trophy to celebrate; they need to try to win one soon to correct the opinion of other people of them as the club that always disappoints.
