Pierre-Emerick Aubameyang staked his claim for a role in Arsenal's Europa League showdown with Villarreal as he struck in a routine 2-0 Premier League win at Newcastle.
The Gabon international, starting his first game after returning from a bout of malaria, struck after 66 minutes - the fifth successive game in which he has scored against the Magpies - to cement the Gunners' 17th win in 18 outings against the Tyneside club.
It was no more than his side deserved from a dominant display which saw them go ahead through Mohamed Elneny's first top-flight goal and never look like surrendering their advantage.
