I knew Arsenal had the harder run-in of the teams battling for top 4 but I've just skimmed through your fixtures and it's harder than I thought. Southampton away is always tricky, Chelsea away, Utd at home, West Ham away, Spurs away and even the home games against the likes of Leeds and Everton who could be battling for their lives - they're all potentially tricky games. And if I'm an Arsenal fan, I wouldn't be hanging too much hope of Liverpool beating Spurs just yet. All things being equal we'll be big favourites in that game but who knows what the title race situation will be like then and the situation with the CL. If we were to lose to City, the title race could be all but over by the time the Spurs game comes around and if we're still in the CL, who knows what side we're putting out in the League.
The game away to Spurs will be huge and a win there will make it very hard for Spurs but lose that and I think you're probably going to have to get two wins from Chelsea, Utd & West Ham, on top of winning the other games you should be winning.
