Chelsea have been offered the chance to sign Borussia Dortmund forward Pierre-Emerick Aubameyang for £70m, according to Sky sources.

The Blues missed out on the signing of Romelu Lukaku to Manchester United and have now turned their attentions to other targets, including Real Madrid forward Alvaro Morata.

Antonio Conte is keen to strengthen his attacking options ahead of the new Premier League season having told Diego Costa that he is surplus to requirements.

However, Sky Sports News HQ understands AC Milan are already in talks with Dortmund over a deal for Aubameyang, while Paris Saint-Germain are also interested.

Aubameyang started his career at Milan, but never made a first-team appearance for the club, instead spending time out on loan.
