Arsenal are undoubtedly a good team. As far as their team's qualifications are concerned, Arsenal are in a fairly good position so far. As their matches are currently on break for the World Cup, there is some concern as to how the team fares after the World Cup. If anyone in the Arsenal team suffers an injury, it will have a special effect on their team later on.
I think the world cup break this time will not only have an impact on Arsenal itself, several other clubs who are recorded as playing in the Europa League will also experience the same thing.
Arsenal are not the only club whose main players have the opportunity to defend their respective countries in the world cup, even if Arsenal fail in the European League they still have the chance to win the EPL title because Arsenal is currently one of the strongest candidates in the Premier League
