Besides losing probably their two best players (I particularly feel losing Song is a bad move), Arsenal have had a decent summer in terms of purchases. They set about their business early unlike last year, and Giroud and Cazorla are very good buys. If they get a good defensive midfielder in then they can be pretty pleased with how things have gone. I don't see them dropping out of the top 4 this season.
Well a hive of activity is hardly the phrase that springs to mind .
And you sort of undermine your argument here a wee bit
