Mashemeji Derby was doing well and it was exciting to watch," Manula told Goal. "However, Gor Mahia have been dominating which in a way has affected the derby. Other teams are struggling to match them [including rivals Leopards] and it has made the derby's spark go down. "It is different with the Kariakoo Derby because both Simba and Yanga are almost at par. It makes the derby unpredictable and as a result, many fans come in large numbers to support their respective teams." The 25-year-old also explained why the Tanzania Mainland League is fast gaining popularity in the East Africa region and the entire continent at large.
