The decision really hinges on the referee imo. His report holds the answer but I also feel he had the most to answer for. Yes Laurie never had corner flags out and there is excuses for that ie new astro Park to them and also the use of flags would have been pointless and been blowing away. But for some one paid to be the official then thsy person should Have carried out all pre match checks ie nets OK, ball OK, flags OK and handing out linesman flags. At that point both teams would have knew where they stood on playing on without them. Seems the safa who provide the ref have to take a share of this as he is an employee of them who should do what he's paid to do.
