I'm curious about how determined Arsenal will be for the Europa League title. So far they have done a great job about balancing the English Premier League and Europa League. They have performed strongly in both of the tournaments. There will be a long break for the rest of the games to start now.
Unless they have to deal with serious injuries after the World Cup ends, I don't expect Arsenal to lose their concentration and start struggling in any of these tournaments. Besides they might add new players to their squad in January as well which would help them a lot in the rest of the season.
Arsenal shouldn't kill two bird's with a single stone and I disagree if they can with the same set of players the transfer window would be open soon, I do hope they can sign player's to back the once they have currently because injuries can also happen and it will cause harm in the long run. If they can they should just focus on the Premier League. Europa league will be very strong when the next season begins
