Lazio have signed Senad Lulic from Swiss side Young Boys for a reported fee of €3million (£2.6m).
The Bosnia midfielder joins the Serie A club on a five-year deal and is looking forward to the challenge.
Lazio will play in Europe next season after finishing fifth in the league and Lulic is hoping the next campaign will prove a success both at home and abroad.
He told Italian media: "I'm really happy. For me, Lazio is a dream.
"I'm at a big club and in a really beautiful city such as Rome.
"Lazio must aim either for the Italian league or in Europe. Both competitions are important, but the Italian league has something more."
