Group G Kick-off 19-45 (BST)
Dan Petrescu expects Rangers to be looking for revenge when his Unirea Urziceni team host the Scottish champions two weeks after inflicting a 4-1 defeat on them.
With his side second in Group G, Petrescu wants another victory against Walter Smith’s side in what he called “the most important match of my coaching career”.
“It will be a totally different match from Glasgow, because Rangers will not underestimate us again,” he said. “They are coming to Bucharest to beat us and to avenge that defeat. They will give everything in attack and any result is possible.
“I have challenged my players to become the first Romanian team to win successive Champions League games. I can’t remember another Romanian team doing this. But I worry about the mentality of Romanian players and it would be a miracle to qualify for the knockout stage.
“I try to motivate my players, but the secret is with them – they will decide their fate, not me. Anyhow, it is the most important match of my coaching career.”
Smith suggested that the home defeat to Unirea was Ranger’s worst ever display in Europe and he admits he would be satisfied with a point to remain in contention.
“The 4-1 home defeat was the poorest display in our European history,” he said. “That’s why I hope we recover and return to our normal level because Rangers are used to performing well in Europe. From what is a very difficult match, we need at least a point to maintain our hopes of qualification.
“It’s a necessity that we improve and I will try to adopt a more attacking and aggressive style of play. I will change the system and play with more attacking players because I also want to change the result and win, even though that it’s going to be very difficult.
“I am happy (Lee) McCulloch will be able to play because the injury problems we faced last time had a negative effect. I don’t know how many spectators will be in the stands, but I remember the last time I was here there was a full stadium and a fantastic atmosphere.”
