Aubameyang joins old teammate Mkhitaryan at Arsenal for club-record fee
Arsenal have completed the signing of Borussia Dortmund striker Pierre-Emerick Aubameyang for a club-record fee.
The Gunners announced the 28-year-old has signed a "long-term contact" at the Emirates Stadium.
The Gabon international, who scored 98 goals in 144 Bundesliga games for Dortmund, is a replacement for Alexis Sanchez following the Chilean's move to Manchester United.
Neither club confirmed the fee, but reports claimed Arsenal have paid around £56million for Aubameyang, whose arrival follows that of Henrikh Mkhitaryan from Manchester United.
His signing is a welcome boost for boss Arsene Wenger, who saw his side's hopes of a top-four finish in the Premier League suffer a setback with a 3-1 loss at struggling Swansea on Tuesday night.
It could also pave the way for the departure of Olivier Giroud, who has been linked with a move to Chelsea.
Tensions between Aubameyang and Dortmund had grown in recent weeks, but the German side's sporting director Michael Zorc said on the club website: "He has done great things for Borussia Dortmund, scored many important goals and is part of the team that brought the DFB-Pokal to Dortmund in 2017. We wish Pierre-Emerick all the best for his future at Arsenal."
