"I am very proud to be here and was very happy to receive President Massimo Moratti's call," Ranieri told Inter Channel as he took charge of his first training session.
"I had a very affectionate meeting with Moratti today. We first met when he was not yet President of Inter and I was at San Siro to watch Milan-Inter."
Ranieri was called after Gasperini failed to win a single match in charge, losing three and drawing one between the Italian Super Cup, Serie A and Champions League.
"I always try to do my best for the team I am working for. When you marry a cause that is what happens, there is total commitment," smiled the lifelong Roma fan.
"Inter are the side we all saw in these last few weeks, as it's not a good time for them. There were injuries and bad luck, but I am convinced this team has the DNA to get back to winning ways and find self-belief."
It is also thought that Ranieri will shelve Gasperini's tactical experiments and especially the three-man defence.
"I believe there are different types of Coaches. I am one who does not believe there is a single winning system, but rather winning players with the rapport created between Coach and squad to rediscover success."
