Rennes fan has gone to great lengths to prove Aubameyang was offside for Arsenal goal

Ainsley Maitland-Niles and Pierre-Emerick Aubameyang celebrate against Rennes

Arsenal are in the Europa League quarter-finals after seeing off Rennes.

The Gunners were the favourites to progress to the last eight of the competition after the draw was made but everything went wrong for them in the first leg in France.

Alex Iwobi scored after just three minutes but they collapsed after Sokratis was sent off in the 41st minute.

They eventually lost 3-1, meaning Arsenal had an uphill task on their hands during Thursday's second leg at the Emirates stadium.

But they put in a commanding performance as they won 3-0.

Pierre-Emerick Aubamayeng scored two on the night and Ainsley Maitland-Niles also got his name on the scoresheet.

However, Rennes will consider themselves hard done by in defeat.

Pierre-Emerick Aubameyang was offside in the build up to Arsenal's second goal v Rennes

That's because Maitland-Niles' goal should not have stood.

Aubameyang clearly picked up the ball in an offside position and his cross was put into the net by Maitland-Niles.

Shortly after the game a Rennes fan went to great lengths to prove that Aubameyang was offside.

Despite clearly being in an offside position, the fan changed the camera angle to a bird's-eye view.

It doesn't seem like the fan has taken the defeat too well.

He has reason to complain, though.

That goal proved pivotal as Arsenal went through to the last eight.

Unai Emery will not care though and he said after the game that he is 'proud' of his players.

"We can be proud of our supporters and players today because it has been a very difficult week," he said, per Sky Sports.

Unai Emery was happy with his players

"We played Manchester United on Sunday and today against Rennes after we were away in the first leg.

"I think today we played very consistently over 90 minutes, being competitive without the ball and very serious defensively.

"It has given us a big confidence on Sunday against Manchester United and today, the same I think with this performance and victory. This comeback was very difficult but I think our reaction is very good.

"Playing under pressure is good. Playing under pressure and growing up under pressure, each player, as a team, they feel difficult moments to give us our best performance.

"For us, today and Sunday, we are aware of playing competitively and I think it is good confidence for us to feel that."
