I will seriously want Arsenal to repeat their success and become a serious contender for title this season only if they are focused. It is not about chasing all the trophies and titles for the season. If Arsenal can pedal down their target to 1 trophy. Be it English Premier League title or the Emirates FA Cup, it will be very nice. They can even decide to drop out from The Champions League and target the Europa League just for them to be able to win title this season.
Arsenal can't just pedal down their target on one league title only. Whereby they have FA Cup, premier league, and champions league trophies to contest for. They will have to play in all three leagues they qualify for, like they do mean to lift the trophies.
When last did Arsenal win one of the leagues mentioned above? They should fight off for the three-league title like it's theirs. They shouldn't feel low on themselves to concentrate only on one because they miss the opportunity last season to win the premier league.
The champions league, premier league, and FA Cup titles are important to add to their name as the trophy lifts for the next season. Any league trophy they are capable of, let them lift it. They shouldn't focus on just one because if they do, it might not go as planned and they might miss the chance to lift another league trophy.
