About 31 percent of the urban Chinese population aged 15 to 59 years has an interest in football after a steady increase in the last three years, according to China and Football, a study published by Nielsen Sports. It explains that interest has been stimulated by government policy as well as large-scale investment from Chinese conglomerates, mostly in real estate, and digital media platforms that are buying up media rights and streaming events. The report also analyzes strategies deployed by European clubs to capitalize on this interest, Chinese investments in European clubs and the dynamics of the transfer market in the Chinese Super League. Fifa's Transfer Matching System indicates that spending by Chinese clubs on international transfers rose by 60.5 percent last year, and the Chinese league made headlines in the summer with the transfer of Hulk, the Brazilian player, from Zenit St Petersburg to Shanghai SIPG for a fee reportedly amounting to $61 million. Among the foreign clubs, Nielsen Sports found that the most popular is Real Madrid with 127 million Chinese supporters. Basketball remains the most popular sport in China, according to the report, ahead of table tennis and badminton.
