Pierre-Emerick Aubameyang made it a record-breaking start to his Arsenal career by scoring in their  3-2 win over Southampton . He cannot play in the Europa League but there are signs that Aubameyang can become very important to Arsenal, writes Adam Bate.

I fear [it could be several weeks] and I hope I’m wrong.” Mkhitaryan has enjoyed an encouraging start to life in north London since arriving at Arsenal as part of the swap deal that took Alexis Sanchez to Manchester United.
