If we decide to focus to win all competition then we might lose all because their is no way you can chase two rat and be able to catch even one its not possible. So it will be better for Arsenal to focus more on the Premier League than want to win two trophies at once if it is possible.
I don’t see anything wrong in them trying to make a chase on the two trophies. If they don’t learn how to fight for two trophies at a time, how will they be able to win against teams that win two trophies or trebles in every season. This is not something that hard to do. If they’re not good as a team, they’ll lose out in all competitions they’re participating in even if they’re just focused on one competition. Let them extend their fight to more than one trophy a season.
I love the way you reasoned this, just that Arsenal sucks too much when it comes to Champions League they don't make it far at all,I think they are mostly after the league title they've won it before they can still win it again if they are willing to work more although they already work enough I don't just know why they fail when it comes to die minute game s... and the funniest part is they make the silly mistakes to clubs that you can't expect maybe they overlooks them don't know, they need to understand there're no small team again and max effort is required for all game.... let's just hope they perform flawlessly this coming season
