Celtic coach John Barnes aims to crowd Lyon out of the UEFA Cup tonight as he urged the Parkhead faithful to recognise his team's fate is in their lungs.

The former England international believes that if the noise level is high enough inside the ground, some of the Lyon players may go missing in action during the second-round second-leg tie.

The French outfit lead 1-0 from the opening leg. But Barnes was encouraged by a stirring display in Lyon, where Celtic created a number of chances without scoring.

With around 60,000 expected at Celtic Park, Barnes senses there is every reason for optimism, assuming everyone pulls their weight to force the issue on and off the field.
