Lazio president Claudio Lotito is delighted with the instant impact of new coach Edy Reja.

Reja defeated Inter Milan in his first game in charge.

"Edy has brought back some calm and serenity," he told Italia 1. "That was not there before."

Lotito then slammed predecessor Vladimir Petkovic.

"Before there was someone whose head was somewhere else!

"Unfortunately, in the end, I found the true identity of this person. Until this year we had an idyllic relationship - then his ego grew and he thought he could do what he wanted.

"We'll have to wait and see how this situation ends."
