It is not enough for Arsenal to finish in seventh place. We have to be knocked out of the FA cup in the semifinals.
Leicester City won the league last season and not playing in Europe helped them (as well as us throwing away our best chance in ages to win the league). This season, Chelski are going to win the
league and they are not playing in Europe. It is very unlikely that we will be able to fight our way back into the top four. And fifth place results in a place in the Europa Cup, which is the best chance to win European silverware, but it is a competition that ruins the chance of a Premier League team winning the title. Sixth place will probably give a place as well, as the odds are that a top four club will win the FA cup. Which means, if we finish in seventh place, we will have a clear run at the league and assuming we can keep our players (and add more quality to the squad), it means we have a good shot at winning it.
So long as Claudio Ranieri is willing to join us as manager...
