Beijing Guoan boosted their Chinese Super League championship charge on Thursday night with 2-0 victory in the “Jing-Jin” derby against struggling Tianjin Teda. The defeat saw Teda condemned to the relegation play-offs in group B with just one point from their opening 10 matches. Elsewhere, Shanghai SIPG recovered from defeat against Hebei China Fortune last time out to record their seventh win of the season and get their title charge back on track. Guoan went in front on the half-hour mark through Zhang Yuning, and doubled their lead at the start of the second half through Renato Augusto. “From the perspective of a 90-minute game, it is reasonable for Guoan to seal the victory,” said Teda head coach Wang Baoshan. “I still want to praise all the team members because they showed high morale on the pitch.” Shanghai SIPG look well on course to join reigning CSL champions Guangzhou Evergrande in the championship round after a 2-1 win against Qingdao Huanghai. Marko Arnautovic smashed in his sixth goal of the season to open the scoring just after half-time, and man-of-the-match Hulk doubled the advantage a minute later. Qingdao grabbed a late consolation through Romain Alessandrini, but they slipped to seventh in group B on the back of their fourth straight defeat.
