Russian club, Rubin Kazan caused a stir in 2009 when they drew 1-1 in the Champion League with eventual champions Inter.
Inter manager, Andrea Stramaccioni said he had done his homework on Rubin and would not be taking them lightly for the clash at San Siro.
"In our group, Rubin Kazan is surely the most dangerous team," Stramaccioni said.
"They have been managed by the same manager for the last 10 years and I really respect this manager working in the Russian football.
"Five out of 11 players are the same who played against Inter Milan in 2009, if I do remember correctly.
"The team has respectful players and Inter Milan has great respect for this match. We'll be facing this match with a high level of concentration.
"Tomorrow's match is going to be very tough both for us and for them, therefore we should be highly concentrated."
Inter will also come up against Serbian side FK Partizan and Azeri club Neftci PFK in Group H of the competition.
