Arsenal face having to allow Olivier Giroud to join Chelsea if they're to sign Borussia Dortmund striker Pierre-Emerick Aubameyang.

The Mirror says Arsenal have agreed a £58m record deal with Dortmund to sign Aubameyang but the German club are adamant they will not let him go unless they get a replacement.

Chelsea are leading a THREE way chase for Giroud - alongside Sevilla and Dortmund - but Arsenal have been reluctant to do business with a top four rival.

Dortmund have looked at Giroud as a replacement for Aubameyang but fear his family do not want to move to Germany and Mirror Sport understands he may yet decide to stay at Arsenal before deciding on his long term future in the summer.

Giroud is open to a move to Chelsea but fears Arsenal will block it, although the Aubameyang twist gives him fresh hope.

Dortmund's other options are Chelsea's out-of-favour striker Michy Batshuayi and also former Cologne forward Anthony Modeste who is now in China. It is believed Batshuayi has agreed terms with Dortmund.

But Chelsea will only allow the Belgian to leave if they can find a replacement - with Giroud now top of the agenda.
