How it happened
Fabio Abreu decided this one, scoring twice for Beijing Guoan in a 3-0 win. The forward converted a penalty in the fifth minute and struck again in the 62nd.
Between those goals, S. Erjini'ao made it 2-0 in the 32nd minute, so Qingdao Hainiu went into the break two behind with little to hold on to. Abreu's second, 30 minutes after the interval's restart, ended any prospect of a comeback. No red cards were shown.
The numbers
Qingdao Hainiu had 13 shots to Beijing Guoan's 12, but only three of them hit the target, against seven for the visitors. Expected goals read 2.5 for Beijing Guoan and 1.74 for the hosts, an estimated figure that suggests the margin flattered the winners slightly. Beijing Guoan held 65% of possession and won four corners to two.
Abreu earned a match rating of 8.7, the highest on the pitch. He had 21 touches and three key passes in his 65 minutes. Defender Guilherme Ramos followed with 8 from 142 touches, and Uroš Spajić took 7.8 from 112.
Pengfei Mu kept the score down for the hosts with four saves and a match rating of 6.9.

For Qingdao Hainiu the picture is bleak: ten defeats from their last ten matches, seven goals scored and 28 conceded. In the all-time head-to-head Beijing Guoan now have eight wins to the hosts' three from 17 meetings, with six draws.
