Madjid Bougherra has urged Rangers to ensure their home form improves dramatically in Europe. The Scottish champions are clearly still smarting from their efforts last season, which saw them finish bottom of the group without a win.
But Bougherra insists Rangers are a different prospect from 12 months ago.
"We have more experience than we did last year," he said.
"We have an obligation to win the three points if we want to qualify.
"We have a winning mentality and we have the capacity to win and we need to give everything to have no regrets.
"All the players have big motivation. Last year we lost everything, on Wednesday we have to prove that we can do something in Europe and that we have the quality.
"It's more about experience. Last year we weren't afraid but we didn't know what sort of football we were going to see in the Champions League.
"Now, we know the Champions League tactically and we need to do everything as a team."
