Arteta wants Emirates crowd to turn belief into Arsenal's title-defence edge

Mikel Arteta is urging Arsenal supporters to swap last season's nervous energy for belief as the club begins its first title defence in 22 years. The manager told BBC Sport the club "learned from the past" that a strong stadium atmosphere lifts players and makes it "a joy to witness and play football in." Arsenal have not won back-to-back league titles in over 90 years.
