Arsenal confirm Pierre-Emerick Aubameyang has joined in £56million deal from Borussia Dortmund

ARSENAL have finally completed the £56million signing of Pierre-Emerick Aubameyang.

The Borussia Dortmund striker has been linked with a move to the Emirates all month and the club have now confirmed his capture.

Aubameyang's move is now likely to allow Olivier Giroud to complete his switch to Premier League rivals Chelsea.

Aubameyang, 28, was spotted arriving at Arsenal's training ground on Tuesday after getting a private jet to Luton Airport earlier in the day.

He completed a medical this morning and agreed personal terms with the club, with his wages set to be worth £180,000-a-week.

And it will mean Aubameyang will link up with former Dortmund team-mate Henrikh Mkhitaryan, who joined from Manchester United earlier in the month.

Dortmund have found a replacement after Chelsea striker Michy Batshuayi joined the club on loan.

And that means Giroud can leave the Emirates for Stamford Bridge in a £20million deal.

The Gunners accidentally leaked the signing in a night of errors on and off the pitch after posting a video of Arsene Wenger talking about Aubameyang.

The French boss, speaking after the 3-1 Swansea defeat, said: "Yes, it's good news.

"We need people who can give us more offensive power. We aren't efficient enough going forward.

"I'm convinced he will bring us that.

"He has a big challenge in front of him, he wants to win the Premier League.

"I believe he's welcome. I believe that's absolutely good news for us."

Wenger was then asked about his strengths.

"Overall his pace, his finishing, the quality of his runs, the quality of his reception to crosses.

"His huge physical capacity to repeat runs, which will be important in the Premier League because the physical level is high."
