Lyon striker Karim Benzema expects to come up against a Rangers defensive wall in Wednesday's Champions League crunch match at Ibrox. The teams are level on seven points going into the decider, and Lyon must win as Rangers would go through because of a superior head-to-head record in the event of a draw, after their 3-0 win at Lyon's Stade Gerland. Benzema told www.olweb.fr: 'We have a big match to play at Glasgow. It's a final and we will do all we can to qualify.' The France international continued: 'We know that Scottish teams like to keep it very tight. 'We received a warning in the home game and now it's down to us to go and win this match.' Lyon lost 1-0 to in-form Caen on Saturday but still lead Ligue 1 by four points in their quest for seven consecutive titles. 'Caen have been playing well,' said Benzema. 'They beat Bordeaux and Paris (St Germain). We knew it would not be an easy match, in fact there are no such things as easy games. 'They started the match well and it's never easy to get back in the game when you are a goal down.' Lyon president Jean-Michel Aulas is convinced that his men will beat Rangers and seal their place in the last 16. Aulas said: 'Personally I am convinced we will do what we have to do. Scotland lost to Italy at home and I am sure that incident will have an impact on them (Rangers). 'Rangers will be ultra favourites and sure of themselves against 20 people from Lyon who will not sell their skins cheaply.' He shrugged off the defeat at Caen, saying: 'We wanted to prepare the team for Glasgow by rotating it, but it (the Caen game) did not end as we wanted it to. 'We had no injuries and that's important because the most crucial game is the Glasgow game. Glasgow (Rangers) will be favourites.' Barcelona have already secured the other ticket to the knockout phase while, with German champions Stuttgart eliminated, it is now a straight fight between Lyon and Rangers for the second spot.
