"When the opportunity to join Chelsea presented itself I had to take it", he told the club's website.
"Here there are the type of players who will help him to do what he can do best".
Higuain, who has been capped 75 times by his country, scored just once in his final 12 appearances for Milan.
And so Blues legend Zola, now back at the club as Maurizio Sarri's assistant, stepped in to tell the players to get down on their haunches so the Stamford Bridge faithful could see. "I'm also sure Gonzalo is used to it", Zola said. I'm sure he's going to be looking at defenders, saying "oh those defenders tactically make some mistakes", which is true sometimes.
"He has always produced good numbers wherever he has been".
Sarri had referenced Cesar Azpilicueta, who now wears the armband in the absence of the out of favour Gary Cahill, and David Luiz as "players with the characteristics to be leaders‚" who could "help all the other players to get the right mentality".
Higuain thrived during his time playing for Sarri at Napoli, scoring a Serie A record 36 goals in 2015-16.
Jorginho is just one of a host of players Higuain knows in the Chelsea dressing room.

I feel so proud. "Again, when we see his performances we look forward to seeing more and more". But in the league he has yet to start a game, with his two appearances coming off the bench.
"Twenty years ago, 15 years ago, I would've said coming here, it's a hard age", said Zola, assistant to head coach Maurizio Sarri. He has looked a far cry from the player whose scoring exploits at Napoli prompted Juventus to spend a club-record €90 million (NZ$151 million) to sign him. "There is no problem there".
But Zola is adamant Hazard remains committed to the Chelsea cause and he was pleased with the midfielder's performance against Tottenham.
"I think that Morata is potentially a very important player". The Blues have had a major hole in the centre-forward position all season long, as neither Giroud nor Morata have been able to play to the required level.
"I don't know. He could do", said Zola.
"This is not a team that is desperate, it's a team that needs to add certain qualities to what it already has".
Victor Moses, meanwhile, is close to completing a switch to Fenerbahce.
"Chelsea have given him permission to talk to the Fenerbahce team".
