MANCHESTER UNITED are heading for the bird flu capital of the world. United have agreed to play a pre-season friendly in the Chinese city of Guangzhou on Friday week after being forced to cancel plans to go to Malaysia. Guangzhou is situated in the province of Guangdong, which is infamous for being at the centre of the first-ever outbreak of the potentially lethal strain of avian flu. Visitors to the city are warned they are likely to leave with flu-like symptoms, known locally as a Canton cold, simply because of the level of pollution in the city. 穆里尼奥:我不会用我的任何球员和曼联换
