There are many different combinations  you can try, but a combination I found very efficient is to breed two Cool Fire Dragons. I have two Cool Fire Dragons, one of them being the "Special One" that you get from downloading the app. Anyway. By breeding two cool fire dragons you increase the chances of getting the Soccer Dragon to 50/50.

In the end, it is all about luck and persistence.
