There’s nothing quite like an old-fashioned strike partnership, and right now there is no partnership quite like the Pierre-Emerick Aubameyang and Alexandre Lacazette double act at Arsenal.

The ‘Auba x Laca’ collaboration has made for quite the sight in recent weeks, when Arsenal’s strikeforce has laid waste to Europa League defences with all the grace, skill and precision you would expect for a combined fee of more than £100m.

Valencia were the latest victims to be left sprawled spread-eagle on the turf, staring in shock at the dissected entrails of their own defence. The Spanish side have the third best defensive record in La Liga this season, yet they could do nothing to stop Aubameyang and Lacazette plundering seven goals between them over two legs of their Europa League semi-final.

At times on Thursday night, when Aubameyang netted three and Lacazette scored the other to silence one of the most hostile stadiums in Europe, it felt almost unfair to have players of such obvious Champions League quality playing against Europa League defenders. Between them, the pair have now scored 10 of Arsenal’s last 13 goals in Europe. In all competitions they have a combined 48 goals this season, with no one else at the club contributing more than six.
