Leeds United fans have been warned over "unsavoury and illegal" behaviour ahead of Manchester United's visit to Elland Road.
United travel to West Yorkshire looking to add another three points to their push for Champions League qualification.
There's sure to be an electric atmosphere at Elland Road but Leeds chief executive Angus Kinnear has condemned foul behaviour ahead of the clash with the "eyes of the world" on the game.
"As ever the Elland Road crowd will play a huge part and if we can recreate the cauldron of support we have enjoyed for our most important fixtures under Marcelo’s reign, I am confident it will be the deciding factor," he wrote in his programme notes (via Leeds Live ).

"While the hostility of Elland Road is a definite competitive advantage we would all encourage, let’s not mistake it for unsavoury and illegal behaviour that could mar our reputation and it is not befitting of our club or city.
"The eyes of the world are on our match today so let’s take it as an opportunity to show everything that makes our club great both on and off the field."
Prior to United's opening day mauling of Leeds, six arrests were made in the build-up to the curtain-raiser after clashes in Manchester city centre.
