Frank, a football lover, frequently attended games at his local ground. On one occasion the football was kicked into the stand where he was sitting, hitting him on the head and knocking him out of his seat, causing him to break his arm. Can Frank sue either the local council or the football club, or both, in negligence for the broken arm that he received? What defences, if any, could the council or the club raise against Frank's claim for compensation for the injuries he received, and would they succeed
