Di Matteo guided Chelsea to European glory last season to join a select band of Italian managers to have won the competition.
The Blues still have work to do to make it through to the last 16 this term and Di Matteo is focused on trying to pick up a win in Turin rather than what reception he is likely to receive at the stadium.
Asked if he was returning home full of pride, Di Matteo said: "I'm proud to have led this club to that trophy.
"Wherever we go, it's a moment where we are a good club. We've shown it and we have to show it again."
Chelsea are currently level on points with Shakhtar Donetsk at the top of Group E, one ahead of Juve, and it is a similar tale across Europe as many of the big clubs are yet to secure passage to the next round.
Only Manchester United boast a 100 per cent record after four group games, with the likes of Barcelona, Real Madrid, Bayern Munich and AC Milan joining Chelsea in suffering defeats.
Di Matteo said: "Every year now, it's becoming more and more difficult.
"We had APOEL, who showed how a relatively small club can do very well in the Champions League. Every season, you see clubs surprising in the Champions League.
"It becomes more competitive and difficult every season, and clubs with new investment and traditional clubs like Juventus coming back after many years, often ending up in pots two, three or four. It makes it very difficult."
