Valencia 2-4 Arsenal: 5 Talking Points 

#2. Hat-trick hero Aubameyang and Lacazette a deadly combo

Lacazette and Aubameyang have combined to score 48 goals and create 21 more for Arsenal so far this term

Much has been said about Aubameyang and Lacazette's partnership this season. They've had their ups and downs, but their combination play and their attacking influence has powered Arsenal into their first European Final for over a decade. Within their goals and assists, the Gunners would have nothing to look forward to, after what has been a frustrating campaign on all fronts for Unai Emery's men.

Instead, they find themselves up against a tricky test with Chelsea awaiting them in Baku on May 29 and have a lot to thank their two strikers for - even if they're not exactly the most clinical. Lacazette is one of the world's best forwards when it comes to link-up play and somehow that facet of his game continues to be overlooked. Aubameyang, who has missed a multitude of glaring chances this term, is picking his moments to peak this season - the pair combined to devastating effect as Valencia's backline were carved apart.

Lacazette out-jumped Gabriel, a much bigger and taller player, to win a header and flick it goalwards with Aubameyang lying in wait ahead of him. Auba's sweetly-struck volley flew into the bottom corner and just like that, Valencia were dealt a hammer blow.

Minutes earlier, Gameiro had just scored and you could excuse the visitors for feeling restless, having conceded early on away from home against hungry, fearless opposition. That goal quietened nerves and silenced the crowd at precisely the right time, but they needed more.

Lacazette the creator, Aubameyang the finisher. It should be the other way around but as we've seen time and again, the pair interchange regularly and it makes things more unpredictable for defences to pick up on. Lacazette hit the post after a great solo run and pass by Aubameyang, before he made amends with aplomb after 50 minutes. Picking up Lucas Torreira's threaded pass, his brilliant touch and finish into the bottom corner were ruthless.

Maitland-Niles created another assist with a marauding run down the flank, teeing up Aubameyang at the near post to slot home. He couldn't miss from such close-range but to seal his hat-trick, he slammed goalwards at Neto's near post and wheeled away as the net bulged. Neto couldn't have been better placed and yet was helpless to thwart the strike.

Many questions have been asked about the pair since their arrivals in recent seasons, which is only natural given the financial outlay Arsenal were prepared to unleash for their services. Are they top-tier strikers? World-class? They are Arsenal's best and there's no disputing that, whether they can finish chances or not.

If they are to have much success against Chelsea in three weeks' time, the Gunners need their attacking duo to be firing on all cylinders. Not least against a Chelsea side who are suspect defensively at times, with David Luiz, in particular, a weak link to exploit.
