The midfielder has impressed in the Club World Cup, having joined at the end of last season from Dinamo Zagreb.
He told La Repubblica: "It's a wonderful group. When you're new, you fear that someone might look at you with suspicion, but instead they welcomed me really well.
"At Inter I want to test myself on a new level, on multiple fronts. That's why I'm here. Before coming I spoke with my national teammates: Kovacic, Brozovic, Perisic. They told me to pack my bags.
"They give me tips on life in Milan, but I don't have a house yet, we left immediately. As soon as I signed, I received a nice message from Lautaro."
Let Modric sign for AC Milan
On the prospect of Croatia teammate Luka Modric joining AC Milan, Sucic added, "Let him sign.
"Until then, I won't call him. For ten years I've watched his football, challenging him would be great.
"When I was little I studied him, Iniesta, Xavi, Busquets. I liked Arsenal's game. But I don't want to imitate others. I'd like to be remembered for who I am."
