Was that "real grass"? or "Plastic Turf"? It seemed that many people were slipping especially Chris Klein, although he seems to have a problem running anyways, he looks really awkward when he runs , almost like a giraffe.
That was real grass, brought in temporarily for the match. The sod will be moved in a week to a high school field. They'll bring in real grass again for the ManU-Glasgow match in July.
