The former Chelsea head coach has taken over the reins from the sacked Luciano Spalletti.
Conte returns to coaching for the first time since leaving Chelsea at the end of last season.
The 49-year-old won the English Premier League title in his first season at the club before adding the FA Cup the season after. This, though, wasn't enough for him to keep his job at Stamford Bridge.

Prior to his move to England, Conte coached Juventus to three successive Serie A titles.
"A new chapter in my life is beginning, I'm really excited," Conte said.
"I have chosen Inter because of the club it is, because of how ambitious it is.
"I was struck by the club's transparency and the desire to bring Inter back to where it belongs."
