According to UK news, Arsenal manager, Arsène Wenger, is thoroughly working on Spanish international right-back Héctor BellerÃn's deal extension for Gunners.
Already on a deal with London side until June 2019, the 21-year old player is still tracked by Barcelona FC (which he's been a development area player for, from 2003 to 2011) and Manchester City. But Arsenal seem determined to save a key position in the squad for him, at least for the foreseeable future.
