Jongsanan Fairtex is a great fighter but he hasnt been Lumphinee champion for about ten years but he was brought up from a young age at Fairtex also Neungsiam Faitex won a Lumphinee title around the same time.
Yodsanklai is from Petchyindee camp, which is also one of the top camps in Thailand. The main change that he has had since changing camps is he has a set diet which has helped him move up in weight. Kaew Fairtex has won a Lumphinee and WBC world title and is currently ranked in the top ten at Lumphinee.
Attachai Fairtex and Tee Lek Fairtex have both been Lumpinee champs and Attachai also was named fighter of the year before.
