To the casual observer, Thursday night's second leg was a mere formality, however the game quickly threatened to turn into a nightmare for Arsenal.
With 22 minutes gone, Hosam Aiesh was sent racing clear down the left and he duly fired across David Ospina and into the bottom corner with the aid of a slight deflection off Calum Chambers.

Visiting manager Graham Potter was visibly delighted with that goal and he could hardly contain his excitement just a minute later when his side doubled their lead on the night and reduced Arsenal's aggregate lead to 3-2.
The 'Gunners' defence was left woefully exposed as the visitors pumped the ball forward but it still took a wonderful piece of skill from Ken Sema to spin Calum Chambers and leave him for dead before rifling into the bottom corner.
