Canada's Patrick Chan boasts an undefeated streak that stretches back 15 months. He arrived in France with the season's best score of 273.94 points. He scored 302.14 points at the Canadian championships in January, becoming the first skater to top the 300 mark, but the score wasn't recognized internationally as it was a domestic event. The 2010 world champion Daisuke Takahashi of Japan is expected to be Chan's stiffest competition.
