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.
This current Arsenal side have indeed shocked everyone, they have confirmed this season that the team is improving and can still do better if the top management be willing to invest more money in the team. I'm sure everyone now believes in Mikel Arteta's project and are willing to follow it true. If their players do not suffer injuries in the World Cup, they will be able to continue our fine form when the league resumes.
