Higuain is on-loan at AC Milan from Juventus, which makes the deal a hard one to negotiate, especially in January.
Higuain had his most successful season under Sarri, breaking the Serie A goalscoring record with 36 goals in the 2015/16 campaign.More news: China trade talks extended, 'going very well'

England worldwide Wilson has found the back of the net nine times in the Premier League this season and has registered five assists.
The report details that the Argentina global could make the switch to the Premier League in January, as Milan are prepared to cut his loan spell with them.
"A goal can change things, but if he is to continue here, he needs to take on responsibility", Leonardo said, according to the Mirror.
So, if Giroud was to be toppled by the likes of Higuain, Icardi or Wilson then it would ultimately be taking a significant positive away from Hazard's game and with the Blues man likely to be the driving force to glory this season then Sarri must focus on starting Giroud for the foreseeable future and not aiming to strengthen his frontline.
"He had a tough moment, he has to put it behind him and get to work". Brazilian Leonardo added: "There's no point following rumours and gossip".
The 26-yer-old Spaniard has struggled for form since his £65m arrival at Stamford Bridge from Real Madrid in 2017.
