Miroslav Klose expects Lazio to be battling for the top spots next season after he completed his move from Bayern Munich.
The German has joined the capital outfit on a two-year deal that will see him net at least €2m a campaign.
"Lazio are a really interesting team, with a mix of young players and experienced ones," the Bosman arrival noted.
"I'm really happy with my new adventure. I think the season will be intriguing and I believe we'll be battling near the top of the table.
"I'll look to give my best in this great place for this great team which consists of some very strong players."
Villarreal were also keen on the former Werder Bremen ace, but the Biancocelesti worked hard to net the striker.
"He's a great signing for us," said Lazio sporting director Igli Tare, a former teammate of Klose when they were at Kaiserslautern.
"The negotiations went on for some time. We were tracking him for ages not only because of his ability, but also because of his image.
"His international experience will be fundamental for us. He was a point of reference for Bayern Munich and still is one for Germany.
"To those who claim he is old, time will prove that this was the right choice. I'm sure that he will sweat for 90 minutes to honour this club."
