Arsenal held a comfortable 3-1 lead from the first leg and, despite a shaky start, looked deadly on the break as the picked off Valencia to make their first European final since 2006.
Aubameyang scored the first and third Arsenal goal either side of Lacazette’s effort as the Gunners earned a 3-2 victory on the night, and 6-3 aggregate success to send Unai Emery back to another final as he looks for a fourth Europa League win.
Aubameyang and Lacazette were unplayable at times on the break, with Arsenal clinically dispatching their limited chances while withstanding a powerful start and consistent pressure from the Spanish hosts.
The Gunners were rocked by an early Valencia goal from Kevin Gameiro, but their nerves were settled by Aubameyang, who latched onto Lacazette’s flick on to volley into the corner expertly.
That took some of the sting out of the home crowd but Valencia still had the bulk of the chances until Lacazette looked to have made the tie safe on 50 minutes when putting Arsenal 5-2 ahead on aggregate with a typically cultured finish.
Gameiro’s second just before the hour still managed to ruffle a few Arsenal feathers despite the visitors still leading 5-3 on aggregate, but any lingering doubts were put to bed when Aubameyang added a third 20 minutes from time.
Ainsley Maitland-Niles showed fancy footwork to beat his man on the right and whipped in a fine cross for Aubmeyang to poke home to make it 6-3 overall.
With time ticking away, Aubameyang completed his hat-trick a minute before time to make it an emphatic 7-3 aggregate success.
