Firmani vows to return stronger than ever

But the 30-year-old insists he will return to Lazio stronger than ever.

“I can confirm that I will be back in four months,” he told Tuttomercatoweb.

“I am not saying goodbye to my club and my teammates because I will return.

“Lazio called me to ask me to go abroad to find my form and so I am convinced they see me as important for the future.

“I will stay close to the team and I wish them all the best for the rest of the season.”
