Unai Emery reflected positively on Arsenal's 2-0 UEFA Europa League quarter-final win against Napoli on Thursday, but he reminded his team their work isn't finished ahead of the second leg.
Arsenal took the lead in the tie at the Emirates Stadium thanks to Aaron Ramsey and an own goal from Kalidou Koulibaly.
Per MailOnline's Max Winters, Emery said:
"It's a good result but we have a big respect for them away because the first 90 minutes here we can impose the result, our game plan.
"We suffered sometimes in the second half, and they can control with the ball and the possession—they had one, two chances in the second half.
