But things are slightly different this time around with Iliev opting to take the fight on the condition it was under Muay Thai rules, which utilise the eight-point striking system (punches, kicks, knees, elbows) and the full clinch, rather than the K1 rules they fought under last time.
That won't bother Thompson. If he can put it all together like he did against Hudson, nothing will stand in his way.
The 22-year-old had a chance to secure the world title bout back in June but tasted defeat in a fight for the ages, and Thompson left no stone unturned this time around to avoid making the same mistakes.
Hudson took the Thompson camp by surprise when he came out all guns blazing, but he decided to fight fire with fire.
