Europa League: Four conclusions as Arsenal knock out Napoli 

#3 Sokratis and Koscielny ooze class!

S.S.C. Napoli v Arsenal - UEFA Europa League Quarter Final: Second Leg.

Arsenal, in their last 7 competitive games has conceded only 1 goal, scoring nearly 11. They have played the likes of Man United, Watford, Newcastle, Everton, Napoli, Rennes, Napoli and the defensive duo of Sokratis and Koscielny have been playing massive roles in holding the fort.

Unai Emery was handed a huge blow when he lost both Hector Bellerin and Rob Holding through long term injuries. He struggled to manage back to back wins for Arsenal, often leading to illogical criticisms from the fans as well as the pundits.

However, he took his time and developed Maitland Niles for that right wing back position. He learned the squad better than anyone and with his defenders fit, Unai Emery's side is displaying top-class defending week in week out - thanks mainly to the Greek wall and Captain Kos.
