Armed police will be on patrol for Celtic's clash against Paris Saint-Germain as part of extra security measures for the match.
About 58,000 people are expected to attend the Champions League qualifier at Celtic Park tomorrow night.
Police Scotland have urged football fans to plan their journey in advance, with a number of road closures due to be in place.
Superintendent Mark Hargreaves said: "Please be patient as it might take a little more time than usual to get through the turnstiles. Therefore I would ask anyone who is attending to ensure they get there early - plan your travel in advance.
"As it is such a crucial fixture for both teams, no supporters from either side would want to miss the kick-off. I would like to emphasise that the security measures, which includes the presence of armed officers, are not in response to any particular threat as there is no intelligence to suggest that."
