Griffiths is thought to be on the Jets wanted list and he will certainly have given Gary van Egmond food for thought after his latest outing.

Guoan were already 1-0 up through Yang Hao's 21st minute goal when Griffiths struck 10 minutes later to double the lead.

He netted again six minutes into the second half as the visitors romped to victory. Only two goals in the last 10 minutes gave the hosts the smallest of consolations.

Elsewhere in China, Mark Milligan's Shanghai Shenhua needed a last minute goal to rescue a point against Qingdao while Mark Bridge's Tianjin Teda won 1-0 at Shaanxi courtesy of Han Yanming's 83rd minute goal.
