The world champion added his second ISU Grand Prix Final title to his list of accolades after scoring 189.43 points in the men's free skating event at Vancouver's Doug Mitchell Thunderbird Sports Centre.

South Korea's Junhwan Cha took the bronze medal in his debut Grand Prix Final, achieving a total of 263.49 points.

Despite Chen's victory, he was unhappy with today's performance after missing the quad lutz jump.

"I am definitely not happy with the Lutz, I stepped back on the toe so that I would not miss out on a combo," he said. 

"I definitely need to bump this up to next level, this is not quite where I wanted it to be. 

Chen added:  "I mostly wanted to improve on what I already had in the last competition in improving whether it be adding a new jump or cleaning things up. 

"For the next competition, I will be working on completing the quad Lutz."
