He told Chilean newspaper El Mercurio: "I think you always have to be positive. I have confidence. After some time, two months or a year, I will fight for the position with anybody.
"If I compare myself to them, the difference is huge, but it is because they have been playing for 10 years. I know I cannot do the same as they do now, but I have some things they don't have - I am young!"
The Argentina Under-20 star, who holds an Italian passport, has praised the welcome he has received from his new team-mates.
"People here are so kind," said Di Franco. "I used to watch them on TV and told myself they would be arrogant but it is totally different when you are inside.
"Despite all they have won, they treat you like one of them and you have to treat them the same. If not, they get angry.
"They help you in whatever you need. Whatever they can give to you, they do. I really don't want to wake up from this dream."
"One day, Carvalho called me 'Crespito' because of Hernan, who also played here, but he is the only one who calls me that. The others call me Frank."
