Matri has been a sensation since arriving from Cagliari last month.
He told Tuttosport: "To be honest I have yet to fully realise how big Juventus are as a club, but they are certainly huge.
"I am going through a magical moment: the goal against Inter, the enthusiasm of the fans. But I still have to fully understand what it means to be the centre-forward of such a big club.
"I am someone who lives one day at a time, so I am trying not to live too much in the clouds, but I always set myself objectives and that of playing at the highest level was one of the objectives I set when I first started to play football.
"There is Lecce up next and I am thinking about that game. We'll need maximum concentration for it.
"We have to forget about Inter and think about Sunday. Actually I am thinking about training tomorrow. I told you that I take one step at a time, no?"
