(2013).The validity of the instrument was approved by experts (7 persons - content). The software PLS 3 was used to analyze the data and the relationships between the variables. The findings showed that customer knowledge management had a significant effect on customer voice marketing, differentiation strategy and business performance respectively, and customer voice marketing had a significant effect on business differentiation strategy and performance. Also, differentiation strategy has a significant effect on business performance. The findings revealed that the managers of sports clubs in the country are not familiar with concepts such as customer knowledge management and ways to achieve better performance through marketing and customer engagement.
