Arsenal dispatch Napoli to book Europa League semi place
The win against Napoli was Unai Emery's 50th game in charge of the Gunners.
Arsenal have set up a semi-final clash against Valencia with a comfortable 3-0 aggregate win against Napoli.
A first-half strike by Alexandra Lacazette was the only goal in the away leg, the first goal from a direct free-kick for the Gunners since Thierry Henry against Roma in 2002-03.
Their next opponents comfortably beat Villareal over the two legs, 5-1 on aggregate and 2-0 on the night, with goals from Antonio Latorre Grueso and Daniel Parejo.
