In the middle of the 2009 season, Pei Encai, then head coach of Jiangsu Shuntian, spoke highly of Guan Zhen: "Guan Zhen has made great progress this season. Although he and Deng alternate appearances, his performance is stable after each appearance. This is what I am most satisfied with him. "
August 20 13, Jiangsu shuntian defeated Changchun Yatai 2: 1. Guan Zhen contributed a long pass 80 meters away at the beginning of the game, but was pulled back by his opponent at the end of the game because of his "clumsiness". Guan Zhen's roller coaster performance in the competition made many media question whether Guan Zhen was a god or a demon.
Due to the excellent performance of Deng, another goalkeeper of Jiangsu Shuntian, Guan Zhen didn't get many playing opportunities in the 20 1 1-20 13 season. After leaving office, then coach Dragan apologized to the media: "In my heart, I feel most sorry for Guan Zhen, and I think I gave him too few opportunities. I hope he can stick to it and practice the game well. As long as he works hard, he will have the opportunity to return to the national team. "
