Reports have it that Pierre-Emerick Aubameyang has arrived Arsenal training ground for medicals having been cleared to do so by Borusia Dortmund.
But BBC Sport reports that the deal is not yet done.
According to the report, the German transfer window closes at 1700 GMT on Wednesday. However, for transfers to a German club from overseas, that only applies to lodging contracts with the DFL.
The actual registration is done via FIFA and they have until 2300 GMT to complete that, so, in theory, a contract could be lodged for a transfer that never actually goes through.
