Arsenal will continue to struggle to force their way back into the Premier League’s top four as long as they refuse to address their defensive frailties, says Emmanuel Petit.
The Gunners have collected back-to-back victories over West Ham and Cardiff after opening the season with successive defeats.
Unai Emery has managed to find a winning formula, but his side have been breached eight times in four games.
Petit believes it's those issues, which have carried over from Arsene Wenger’s time at the club, which will ultimately prove to be Arsenal’s undoing and undermine the efforts of their frontmen.
