Thursday sees Torino and Zenit resume hostilities after the latter recorded a 2-0 first leg win in their UEFA Europa League last 16 tie in Russia last week.
Marco Benassi's first-half dismissal led to Torino's demise at Petrovsky Stadium, with Axel Witsel and Domenico Criscito both on target afterwards.
"It will be a Torino side that wants to fight for the win," Ventura said after a 2-0 loss at home to Lazio on Monday.
"We have a negative result to overturn, but that came about mainly because of the early red card."
Racism reared its ugly head again on Sunday after Hulk was subjected to monkey chants by a section of home support in Zenit's 1-1 draw with Torpedo Moscow at Saturn Stadium.
"You can’t understand, accept or explain those things," the Brazil international was quoted as telling Zenit's official website. "This isn’t the first time that I’ve encountered something like this, but each time you just have to ask that everyone respect all of the players, again and again.
"However, in spite of similar things like this, whenever racism does show up, both me and the team try to stay focused on the game."
