The Blues looked set to re-sign Romelu Lukaku from Everton this summer.
He made 46 appearances in all competitions, scoring an impressive 40 goals in the process. The 28-year-old has been accused by the pundits of diving on many occasions, the referees tend to reach for the whistle every time he hits the deck; it has led to a sorry end for the former Brazilian global.
Chelsea boss Antonio Conte is reportedly after a new striker, with the club now in pole position to bring Gabon forward Aubameyang, having missed out on Romelu Lukaku to rivals Manchester United, and with a deal for Real Madrid forward Alvaro Morata proving hard to secure, as reported by the Mirror.

Chief executive Hans-Joachim Watzke admitted in June that Dortmund would consider any bid of €70m (£61.6m), but the club are not actively looking to sell and the Standard's report notes that claims Chelsea were offered the player for £70m earlier this week are "wide of the mark".
There are still four years left to run on his contract in Turin.
Both men are being heavily linked with moves away from Stamford Bridge. The news is still relevant and even more so in the coming weeks however; Lukaku has officially transferred to Manchester United and Conte's eyes are firmly fixed on Italian global Andrea Belotti.
Jose Mourinho has confirmed that Manchester United were interested in signing Alvaro Morata this summer but that the Red Devils could not agree a fee with Real Madrid.More news: G20 communique exposes divide with US on climate policy
