By Sami Mokbel for the Daily Mail Follow @@SamiMokbel81_DM Arsene Wenger defended his decision to field a hugely inexperienced defence as Arsenal crashed out of the Capital One Cup. Dusan Tadic’s penalty followed by Nathaniel Clyne’s 30-yard thunderbolt secured a deserved victory for Southampton at the Emirates Stadium after Alexis Sanchez’s brilliant free-kick put the Gunners ahead. Arsenal’s back-four has been ravaged by injury in recent weeks; Mathieu Debuchy and Nacho Monreal were confirmed absentees for Tuesday night’s clash, while Wenger revealed following the defeat that Per Mertesacker (gluteal) and Kieran Gibbs (hamstring) were only fit enough for a place on the bench.
