A new study from Sportingintelligence shows that the Juventus shirt has been the most popular Serie A shirt worldwide over the last five years.
Worldwide there were 480,000 Juventus shirts sold a year compared to 425,000 for Inter and 350,000 for AC Milan. These figures do not include counterfeit merchandise.
Overall, only three clubs are selling United more than 1 million shirts a year. Manchester United and Real Madrid with 1.4m and Barcelona with 1.15m shirts sold per year. That number surprised me as I thought that clubs sold millions of shirts a year.
England have four teams in the top 10, with Chelsea, Liverpool and Arsenal accompanying Manchester United, while Bayern Munich is the other club to break into the top ten.
