The Ibrox side were expected to ease to victory in last week's first leg at home against Kaunas but a combination of poor finishing and stubborn defending saw the match end goalless.

Kaunas recognised Rangers as favourites ahead of the tie but will now be confident of going through in front of their own fans to set up a meeting with Danish side Aalborg in the next round.

Despite being impressed by Jose Couceiro's men, McCoist insists Rangers should be able to avoid the disappointment of crashing out of Europe tomorrow night.

"I said all along that I thought they would be a reasonable side and I thought they were a better side than the team they had at this stage last year," said the Rangers assistant manager.

"The noises coming from their camp, as you would expect, is that they fancy their chances. But, of course, we do too.

"They also had a few chances at Ibrox but I think it's safe to say that, if we had put one of our chances away, we would have won the game comfortably.

"It wasn't to be and we now have the hard work to do on Tuesday."

Manager Walter Smith insists the approach Kaunas adopted for the game in Glasgow was what he expected - what he had not expected was the lack of cutting edge from his own team.

He said: "We weren't surprised by them at Ibrox - they set out their stall in the manner I felt they would do and their coach has definitely had a good assessment of what he had to cover to make it difficult for us to play.

"They have decent defenders and a good goalkeeper and we knew they would be able to make it a difficult game at Ibrox.

"It will be a big test for us in the sense that we haven't reached the level of play that we did last season or the edge in our game. We have to make sure that's the case tomorrow night."

Carlos Cuellar is unlikely to recover from a calf injury in time, despite travelling with the team, meaning Kirk Broadfoot is likely to deputise in central defence again, while options remain limited in midfield due to the continued absence of captain Barry Ferguson.

Smith is spoiled for choice in the striking department, with Kenny Miller, Jean-Claude Darcheville, Kris Boyd, Andrius Velicka and Kyle Lafferty all vying for places.

"We are more or less settled and know what we will do," said Smith.

"That's the manager's prerogative and whether it is the right choice or the wrong choice always depends on the result."

Kaunas' star man Ledesma is likely to play a key role after shaking off an injury to make a reasonable impression at Ibrox.

Smith said: "I think he is a player we will have to watch. I don't think he looked as though he was 70% fit at Ibrox, he looked fit to me until nearer the end of the game.

"These are the problems that Kaunas can cause us if we allow them."
