Career
Wu Xi started his football career with Hebei Tiangong in 2008 when the club was formed and joined the third tier. While the club only played one season in the division, Wu"s development particularly with the Chinese national youth teams was impressive enough for top tier side Shanghai Shenhua to be interested in his services, signing for the club on 17 November 2009. Before the start of the 2013 season, Wu transferred to fellow Chinese Super League side Jiangsu Suning.
He made his debut for the club on 26 February 2013 in a 5-1 loss against Football Club Seoul in a 2013 AFC Champions League group match, coming on as a substitute for Lu Bofei.
In 2007, Wu was considered impressive enough to be selected for the Chinese under-19 national team and would take part in the 2008 AFC U-19 Championship. A regular with the side, he could only aid the team to the quarter-finals after he personally missed a penalty in a penalty shootout against Uzbekistan.
On 24 December 2014, Wu was named in China"s squad for the 2015 AFC Asian Cup in Australia.
