Arsenal are through to the last eight of the Europa League.

After giving themselves a sizeable mountain to climb, the Gunners beat Rennes 3-0 at the Emirates to claim a 4-3 aggregate win.

Pierre-Emerick Aubameyang struck twice, with Ainsley Maitland-Niles also on the scoresheet, grabbing his second senior goal for the club.

It was a well-deserved win and it was Unai Emery's changes late in the game that made a huge difference.

Alex Iwobi and Henrikh Mkhitaryan came on for the final 20 minutes and added an extra edge to the Gunners both defensively and going forward.

Mkhitaryan played a key role in Arsenal's third goal and in addition to his fine cameo, Iwobi made himself a bit of a social media legend just before full-time.

Footage quickly went viral of the Nigerian winger taunting Rennes' Hamari Traore about his 'smelly breath'.

You just can't help but laugh.

If a story emerges that Iwobi personally sent a packet of chewing gum to the Rennes dressing room after the game, then football may have officially peaked.

Arsenal now go into the international break in a very healthy situation, something that did not look likely back at the start of the year.

Emery's side are currently fourth in the Premier League, one point behind Tottenham in third and are in the quarter-final's of the Europa League.

Their star men are all starting to hit form as well and Emery seems to have found his best team and formation.

The Gunners have thrived in a 3-4-1-2 formation in recent weeks, with Sead Kolasinac and Maitland-Niles providing fantastic service from the wing-back roles.

Aaron Ramsey, Mesut Ozil, Alexandre Lacazette and Aubameyang are all linking up well, while Iwobi and Mkhitaryan are game-changers from the bench.

They've even looked more sound defensively of late, a sign that things appear to be clicking in the Emery era.
