According to Italian outlet Sport Mediaset (via Metro), the Blues will pay €60 million (£53 million) to sign the Argentinian, and the move will be officially announced after Maurizio Sarri has been appointed the new Chelsea manager.
If Higuain moves to Stamford Bridge in a cash deal, though, Spaniard Morata will likely still look for a route out of west London as he would almost certainly lose his starting spot in the side.
The 30-year-old Higuain is on holiday after Argentina were knocked out of the 2018 FIFA World Cup.
He endured familiar woe playing for La Albicelste in Russia as he failed to score a goal in three appearances, per Fox Soccer:
But his club record is enough to get Chelsea fans excited about his imminent arrival.
In the last three Serie A seasons, he has netted 76 goals, 36 of which came in his final season for Napoli, during which he was playing under Sarri.
If the Italian manager can inspire the same from the former Real Madrid man next term, he could be devastating in the Premier League.
The main concern for Chelsea is Higuain's age. It is a big risk to shell out over £50 million on a player who will be 31 in December, and there are some who will likely feel he is already past his best.
