The France international has joined the Giallorossi on a season-long loan, with a view to a permanent switch to the Stadio Olimpico next summer.
Yanga-Mbiwa is looking forward to plying his trade, primarily because he feels he will be able to play with the ball at his feet for the first time since leaving Montpellier for Newcastle in January 2013.
"[In England], they don't have the same way of seeing things," the defender told reporters on Thursday. "It's all based on physicality.
"Here [in Italy], I believe that things are different. One plays more with the ball. The Italian league is much more similar to the French."
Yanga-Mbiwa also admitted that he is also excited by the prospect of working with Roma coach Rudi Garcia, revealing that the former Lille boss played a major role in his decision to move to the Italian capital.
"I know Garcia already," he versatile 25-year-old centre-half explained. "He was one of the greatest coaches in France.
"He convinced me to come here to win the championship. The coach was the first to call me.
"He had already noticed me when I won the title in France with Montpellier and he knows what I can give.
"I'm hungry for trophies and victories; I've come to Roma for this. We certainly have a great squad and we will do everything to achieve great goals."
