The 31-year-old Argentina striker played under Maurizio Sarri at Napoli and a reunion with the Chelsea boss is on the cards.
Chelsea have reportedly agreed on a temporary deal to sign Gonzalo Higuain from Juventus this month, though the formalities are slowing down the player's anticipated move to the Bridge.
An agreement has been reached and the forward is due to join Chelsea on a six-month deal.More news: Duke Star Zion Williamson Suffers Eye Poke During Florida State Game
AC Milan coach, Genaro Gattuso is positive that Higuain is keen to leave the San Siro, saying "when a player makes up his mind it becomes hard to convince them otherwise".
Romano also reported that AC Milan, the club at which Higuain is now on loan, is okay with the transfer.
And speculation regarding his future gathered pace on Wednesday after he was missing from Milan's team photo in Saudi Arabia ahead of their meeting with Juventus in the Supercoppa Italiania in Jeddah. "We did everything we could to get him better, but he didn't sleep much, so I preferred a fresher player".
Whoever signs James later in the month, the Colombian will only spend the rest of the season in England except they negotiate a permanent deal with Madrid before the start of 2019-20 season campaign.
