This is not surprising to me, because Arsenal has always dominated most games and I believe that this is there season. They have made some good signing and I am expecting so much from them. I will really be disappointed if they don't win a major trophy this season. Arsenal has always been a contender for the league for the past 3 seasons and I am confident that they can go a step further to win the premier league this season.
This is the best season so far that Arsenal are preparing their squad. I feel they have the potential of competing as a contender but the problem is that the big clubs are also doing worse than them. Liverpool are making signings same with Manchester City including Chelsea and others, teams are getting ready for the season, there might not be dull moment in this season Premier League, i expect the GD to be very small this season.
Arsenal preseason shows the progress, before the season begins there will be much development, more ball came inside opponents box during the match against Milan, despite not converting chances if they work continuously on that aspect, it will be a nightmare for any team once Arsenal enters the 18 yard box.
