There is one last thing left for Arsenal to prove now. It is their games against Manchester City. If they get positive results against them as well then I don't see any other hindrance for them to make it to the league title for real. I know that Manchester United and Newcastle are also in a similar distance to Arsenal in the standings. But in the long run I see Manchester City can compete with Arsenal the most.

Even Manchester City can't keep up with them interestingly. They have had serious issues in not only some big games but also against smaller teams. I won't be surprised if the gap with Arsenal gets bigger in time.
