Is not Arsenal always doing it ever since more than 20 years ago? It's nothing surprised when they're trophyless again. They are a club with trophyless specialization.
Unless Arsenal throw away the ambition to win the title in all competitions and prioritize one competition to win the title is the best choice. Unfortunately Arsenal can't do this and every season always starts the season very well. After that at the end of the season Arsenal always loses its mentality and performance to be one step closer to getting the EPL trophy. So whatever happens I will never believe in Arsenal who can win the title unless another team like Liverpool who I admit can win the title as you said.
