The former Napoli boss is looking forward to getting started at his new club and is keen to help them back among the elite next term
The Giuseppe Meazza side had to settle for ninth spot in the Serie A table after an inconsistent campaign, in which they suffered a Europa League exit at the hands of Tottenham and a Coppa Italia semi-final defeat to Roma.
Andrea Stramaccioni was replaced with Mazzarri at the end of the campaign, and the former Napoli boss is determined to restore Inter to their rightful place in the footballing pantheon.
"Inter must get back to being competitive again. The fans should be proud of watching a team that never gives up. I have no problem taking on responsibility. I want Inter to be competitive again as soon as possible," Mazzarri said at a press conference.
"You can talk about a 'project' after you've got off on the right foot. You have to set out with clear ideas. Right from the start you must drum in the idea that Inter comes first, personal interests second.
"I'm a coach and it's my job to focus on getting the best out of the players the club provides me with. I'll have a good look at the players during our training camp, then I'll speak to the club and they'll deal with transfers."
Mazzarri left Napoli this summer after four years in charge of the Partenopei.
