Gunners are trophyless this season because they've failed in their fullest capacity to win matches and obtain greater heights in England. We should pour all blames on Mikel Arteta for his incompetent capacity? I don't think so because since his arrival as Gunners headcoach, he has done his best for the club to excel. Arsenal will go again next season, they will keep trying until they succeed in nailing important goals for the club. This season was a wonderful one for Gunners despite them been eliminated from all elite tournaments.
Arsenal missed a lot of trophies due to the Arteta's incompetent. He's unable handling the problems appeared in the club. His stubbornness not to sign a new striker obviously become one of variable why his club missed all of trophies. Being a trophyless club alone wihle your competitors are almost getting trophies is just painful.
He's a headcoach of club, and must be responsible for everything that happened in the squad. He and his squad must take the blame
