Speaking to Sky Sport Italia, Marchisio said: "Against Zenit we played like we did in our great run of form prior to the Inter loss.
"We played with great character and we played good football. We didn't have this frame of mind against Inter, Marchisio declared.
In St Petersburg we suffered in patches but we were also able to create. We took some risks but we created a few chances and at the end of the day we came home with a satisfying result."
