I so much believe in arsenal and the new players they brought to strengthen the squad more knowing that their will be good improvement but looking how the Champions league game will be it will be difficult for arsenal to win champions league. Their are strong teams that will be participating in Premier league and other leagues. I believe arsenal will have a good game in champions league but can't win the league. Manchester City are still the favorite team to win champions league next season.
Arsenal's first season was with full of surprises and unpredictable results, but now things are much better as their coach Arteta able to fix their problems which create problems for them in last season, and now they are going to have better result in this season even now their presence in Champions League is surely created some pressure but still they will try to have better results in Premier League because this is their main focus they already have few quality players which are going to have good impact on performance of team.
In last season no one was expecting them to have second spot in league table and now same situation but most chances they will be able to give surprises because again in this season few teams from Premier League are going to have problems which they fail to fix and things are going from bad to worse, but Arsenal is surely team to watch again in this season.
