Hector Bellerin is adamant Mikel Arteta has made important changes at Arsenal but admitted they may have gone unnoticed by fans and pundits.
It was a difficult first full season for Arteta as the Gunners missed out on a place in Europe for the first time in 25 years after an eighth place finish in the Premier League and a semi-final exit in the Europa League.
Arsenal suffered a dreadful run of form before Christmas and an inconsistent finish to the season raised further doubts over the Spaniard's future.
