Chelsea and AC Milan will fight it out for the signing of Borussia Dortmund striker Pierre-Emerick Aubameyang.
The Gabon international has become one of the best strikers in Europe after finishing top scorer in the Bundesliga ahead of Bayern Munich's Robert Lewandowski last season, managing 31 goals in 32 league appearances.
According to Italian publication Corriere dello Sport, Milan want the 28-year-old to lead their planned revival in Italian football, having already spent heavily during the summer transfer window.
Milan have already signed centre-back Mateo Musacchio, full-back Ricardo Rodriguez, forward Andre Silva, attacking midfielder Hakan Calhanoglu, right-back Andrea Conti and 17-year-old Przemyslaw Bargiel this summer.
They have Carlos Bacca available up front but the Colombia international's place in Vincenzo Montella's side is under threat after scoring 13 goals in 32 Serie A appearances as the Italian club finished sixth in the league.
Sky Sports sources also claim Milan are willing to make Aubameyang the highest paid player in Italy, with a sum of £135,000-a-week being mooted for the former Saint-Etienne forward.
Chelsea wanted Everton's Romelu Lukaku and now have serious business to do in the transfer window after the Belgium international elected to join Manchester United instead, with Diego Costa certain to leave after being told he was not in Antonio Conte's plans.
Costa was apparently told via text message that he is unwanted at Chelsea and the Blues now need a striker to lead their Premier League title defence next season, with Michy Batshauyi used sparingly during his first campaign in England.
