Taty Castellanos is eager to learn from Ciro Immobile at Lazio.
The Argentine striker moved to Lazio this summer from Girona.
Castellanos said: "I think I can learn a lot from Ciro.
"We have a good relationship, we talk a lot. We can grow together, I'll wait for my moment. Argentina would be a dream, being part of this club could help my eventual call-up.
"I'm a player with character, I understand the game well with or without the ball. I know how to play the field and I want to try to carve out my space. I can't give a figure on goals, I'll do my best to help the team achieve the best results."
New Lazio sports chief Angelo Fabiani said of Castellanos: "He's a footballer who will be talked about a lot, we studied him for a whole month. We convinced ourselves of the potential of Taty who even before his technical skills has a strong mental aspect."
