St Johnstone manager Simo Valakari has been speaking to the media before Saturday's Scottish Premiership visit of Falkirk. On Hibs head coach David Gray becoming the first Premiership managerial casualty of the season, Valakari says: "He is my colleague and of course I feel for my colleague", adding it shows "the ruthlessness of this business". Valakari believes there is a "lot of room for improvement as well".
