You've got the squad to win the league this year. You've addressed the attacking issues you had and have strengthened your defence and midfield further as well. The media were so focussed on us losing our usual level and the rags being filth that they missed the fact the dippers only got 84pts last season. Furthermore, only 75pts were needed to win the title. That's a significant decline from previous years.
Liverpool were poor defensively and still are. They didn't address their weakness and will suffer the same fate you did.
The only question mark is us. Will we gel in time to get the results to push you? Most on here are measuring us against where we were but I don't think we need to be as ruthless as that. I would expect you to get around 86pts. That means we don't need the improvement in results that some probably perceive we do. It's crudely turning one loss into a win over a 10game block. There were 5pts left out there against Brighton and yourselves already this season...so fine margins.
The reason I think your total will be in that range is purely because of the pressure on Arteta to secure a trophy. That means he can't throw any competition and naturally that means he'll pick stronger teams than are perhaps necessary, which could see your results in the league suffer.
