Career
Shandong Luneng
Guan would make his senior club debut on March 16, 2003 for Shandong Luneng in a league game versus Yunnan Hongta. His appearance was to make him the youngest goalkeeper to ever appear in the top tier in the Chinese league system, however this record was later broken by Wang Dalei. After his debut he would play understudy to Zong Lei and Deng Xiaofei for several seasons, however Shandong Luneng would bring in Li Leilei in the 2006 league season and Guan was loaned out to Chengdu Wuniu.
Chengdu Wuniu
Guan would join second tier club Chengdu Wuniu on loan in 2006 to gain more playing time but failed to make it as their first choice goalkeeper.
He would return to Shandong Luneng where he would once more be used as a third choice goalkeeper. Unable to improve unpon his position Shandong Luneng were willing to let Guan leave at the end of the 2007 league season.
Jiangsu Sainty
He transferred to second tier club Jiangsu Sainty at the beginning of the 2008 league season and was immediately placed as their first-choice goalkeeper within the team Shijiazhuang Ever Bright
In January 2015, Guan transferred to fellow Chinese Super League side Shijiazhuang Ever Bright.
Guan was the first choice keeper for the Chinese U-20 team before the 2005 Fédération internationale de football association World Youth Championship that was managed by Eckhard Krautzun, however he was ruled out after suffering an injury before the tournament by his own teammate Wang Yongpo.
His performance was good enough for him to be tried out in the 2010 East Asian Football Championship and then later included in the squad for the 2011 AFC Asian Cup.
