Arsenal have the performance to beat any team right now, and this is the right time for them to make things possible for themselves; they don't have any weak positions right now. The Arsenal squad is strong right now, and I hope they will maintain this performance till the end of the season to get the title. The season just got started; they still have a long way to go,
but even with that, there is a possibility that Arsenal will have changed for good this season since they have already strengthened their attacking position, so let's continue seeing Arsenal at the top of the league this season. Arteta will surely surprise us this season.
I know Arsenal currently has got a really good form but you cannot generalized the fact that they will be able to defeat any team now, they can likely meet Madrid in the champions league and except they have luck on their side, they are definitely not winning that game even in their best form with their key players present. Definitely this season Arsenal is coming with so much improvement as they want to make sure to get a trophy by the end of this season and I don't doubt their abilities but then it may not go with an unbeaten record that I know for sure.
