In terms of the challenge to Patrick Chan, it was a very topsy turvy season for his 4 main challengers - Yuzuru Hanyu, Daisuke Takahashi, Javier Fernández, and Denis Ten. If fact, none of them provided a consistent challenge. Whilst Hanyu set world records in his short program, he struggled all season long to put together a good FS performance.
Dai was good in the GPF and at the WTT, but could only finish 6th and 7th respectively at Worlds and at the 4CC.
Javier Fernández beat Chan at Skate Canada, but was unable to beat Patrick the rest of the season. He did, however, win Europeans.
Denis Ten came mighty close to winning the World title. Indeed, in the opinion of many he was the rightful winner. However, his form during the rest of the season was not impressive.
So, come next season, which of these 4 skaters will provide the greatest challenge to Patrick Chan?
