The Bhoys have already qualified but Neil Lennon has insisted that his side are not taking the game lightly.
The Hoops are in great form at the moment, having won 12 games in a row. And Lennon doesn’t want to disrupt the momentum.
Cluj need at least a draw at the Stadionul Dr Constantin Radulescu on Thursday night to secure the second spot in Group E.
Lennon has decided to rest several key players for this game after already being assured of the top spot.
However, Petrescu insists they should still be stronger than his own Romanian champions.
