Alexandre Lacazette scored a brace and Pierre-Emerick Aubameyang netted late on as Arsenal came from a goal down to establish a 3-1 first leg lead in their Europa League semi-final tie against Valencia.
A close range header from Mouctar Diakhaby gave the Spanish side the lead and set hearts fluttering at the Emirates Stadium as the Gunners struggled to live with their visitors.
But Lacazette soon levelled when he stroked into an empty net after being found by strike partner Aubameyang, before he bundled home from close range with head after the visitors failed to clear.
The Frenchman passed up plenty of other chances for the Gunners the extend their lead, but they'll take a two-goal advantage to the Mestalla next week after Aubameyang fired in late on.
Here's how the Gunners players rated.
Petr Cech 7
Shkodran Mustafi 6
Laurent Koscielny 7 (Nacho Monreal 82, 6)
