#4 Get a new Number One
Arsenal have, for a long time, been a club that have stuck with one classy goalie until he has needed to be replaced and that time has come again.
Petr Cech has been one of the great goalkeepers in the Premier League but it is safe to say that Chelsea and not Arsenal saw the best of the Czech shot-stopper. Brought in to add experience, know-how, and calmness to a very skittish backline, Cech has been good but not great, with the horror show of a season he has had the clearest indication that his days are numbered.
Second choice goalie David Ospina, who is the first choice for the Colombian national team, has also failed to show that he has what it takes to be the undisputed number one for a trophy-chasing team like Arsenal and the less said about third choice goalie Emiliano Martinez, the better.
The new manager will need to do better than Wenger in this regard and given that quite a few of Europe's big boys e.g. Real Madrid and Liverpool will be looking for new goalkeepers this season, urgent attention must be paid to this.
