Satisfaction doesn't fill any manager's mind when it comes to football. Arsenal does have top strikers in the club, though Mikel Arteta keen on bringing in tough decisions and replacement for the frontlines, he needs new set of frontlines that would do the job of a  striker and not some random players that simply foot in the space and they celebrate. Mikel Arteta is not satisfied with his team's present results, they have to fight really hard to become the best among the best, that's the goal for every club in EPL this season. Arsenal frontlines are build with high quality players that are confident infronts of goals this season.
