England forward Rooney, criticised in the past for swearing and spitting, was electric last season but struggled at the World Cup and has been in poor form this term while allegations about his private life have filled the tabloids.
"Rooney is a really great person, he always gives me advice, but he's a bit working class and vulgar," Macheda told Thursday's Gazzetta dello Sport while in Italy with the Under-21 team.
"I want to improve in Manchester, when I'm more mature I'll be able to make choices. The rumours about Lazio please me but I don't think I will go," the 19-year-old said.
"It hurts to not play especially when the other two are not doing great," Mannone said.
"I'll see, here the situation at Arsenal is not normal, I'd do six months on loan to play. AC Milan has been a dream since I was a kid."
