Inter came back from a goal down to win 3-1.
Strama said: "Inter conceded this goal when I had barely even got on to the bench and that turns the tide, but over time we grew and I have to say this is the first time I have seen Juve under such pressure on their own turf. Having said that, Juventus remain on top of the table and are still the Serie A leaders.
"The greatest day of my career? That was when President Massimo Moratti chose me to lead Inter. This result will send a signal, as we came here to the Juventus Stadium against a team unbeaten in 49 rounds and attacked them with a trident."
