Arsenal have launched a massive bid for Borussia Dortmund striker Pierre-Emerick Aubameyang, according to French sources.

France Football says the Gunners have approached Gabon international Aubameyang after submitting a £28m bid.

Dortmund insist he is not for sale and have tabled a contract extension.

But it is claimed Aubameyang favours a move to the Premier League.

Arsenal are not alone in their chase for the 26-year-old as north London rivals Tottenham are also on the case.
