Gonzalo Higuain has made it clear to AC Milan he wants to leave for Chelsea and could play his final game for the club in the Italian Supercoppa against Juventus, the club in the centre of this triangular transfer.
Maurizio Sarri has made it clear to the board at Stamford Bridge that he is desperate to sign Higuain who he sees as the key to solving what has become a problem in front of goal.
Milan have reached a point where they are prepared to let the Argentina international leave if they can find a replacement, and have made a move for Krzysztof Piatek at Genoa.
Chelsea have been working for weeks to strike a deal with Juventus which will persuade the Italian champions to call Higuain back from Milan, where he was on loan for the season with a view to a permanent move in the summer.
Negotiations have been further complicated by the fact Chelsea want to move Alvaro Morata to create space in the squad and on the wage bill.
There has been no shortage of interest in Morata from Spain and Atletico Madrid are established as the latest favourites to sign the former Real Madrid striker who has lost his way in the Premier League.
