For the fourth time this season, nothing separated St Mirren and Dundee United in general play. There was Richard Taylor’s header cleared off the line, Mikael Mandron rattling of the underside of the bar, but it was Toyosi Olusanya’s afternoon that will keep the Paisley faithful awake for the foreseeable. First, sent clean through by a lovely lifted Mandron ball, he could only find United keeper Jack Walton’s feet when the bottom corner beckoned.
