In this season Arsenal is doing amazing job, and we can expect improvement in coming weeks but can they keep this momentum, and we will be able to watch them as winner of the two titles because they are capable of having amazing stuff and new player's entry can bring more success with good and strong competition.
As Arsenal have started the season and continued their form, they are undoubtedly the frontrunners to win the title this season. Arsenal is financially sound. I think they will try their best to win the title this season. And if necessary, they will spend money to add new talented players to the squad. Arsenal is still 5 points ahead of Manchester City. They will definitely want to maintain this gap.
Given the competitive competition in the Premier League, they still need to strengthen the squad they currently have. Also they definitely want trophies here, so it's only fitting that they spend some money to sign some quality new players. We are still waiting for their opponents in the Europa League at this time, and of the several names that are there, Arsenal are one of the favorites to win the title this season. The compactness and teamwork they showed made them have the upper hand to win the title.
