Hector Bellerin knows Arsenal need to improve in front of goal, but he's confident improvement will come, thanks to head coach Mikel Arteta's tactical acumen. Arteta took over on December 26, and Bellerin believes the club's former captain has already changed the Gunners for the better.
Bellerin spoke to the club's official website during warm-weather training in Dubai: "Mikel has always been very tactical in his work and in his whole life, he's very professional with very clear ideas. It's very early doors in time.
