It depends on what risk you are assessing though, is 10 million mission critical - no. Does 10 million and Dele Alli give you a better chance of not taking a 100 mill drop in revenue if relegated - when goals and creativity are a source problem! Then you are into from PM point of view - business case and quality assurance, cost/value analysis reviewing alternates - say is paying £15 mill for Dele in fee and wages, better then buying say Stuart Armstrong for £15 mill from Southampton, or £40 mill on JWP in addition to Alli's wages.
Again it depends on the risk you want to analyse - is it saving money or is it staying in the league - risk management- it has many systemic variables and impact which again is systemic.
