Roma unveil 'right man' Gasperini as new coach
Gasperini, 67, joins Roma on a three-year deal after turning Atalanta into one of Italy's best teams, winning the Europa League last year.
Gasperini said he chose Roma over Juventus because he believed they had everything in place to grow.
"The club convinced me because it is a great challenge. I needed to have a big challenge and to come to an environment with great passion," he said.
"In my opinion, all the conditions are there to achieve this."
He also said his first task would be to win over the fans with an attacking style.
