The top fighters of the same era, never faced each other in the ring.

They had some similar opponents and outcomes. Both outclassed Valuev, both handled Ruiz, both were dismantled by Wlad.

Both of them were skillful and technical operators. Both could box, both could hit hard and both had solid defensive skills. Chagaev was more keen on fundamentals. Haye was faster, he had better reflexes and overall was a slicker boxer. Chagaev had a better chin. I guess, it would be a tactical affair. Chagaev would push the pace, Haye would use his jab and superior footwork to keep Chagaev outside. Chagaev would sharpen from time to time, but Haye would win the majority of exchanges. Haye would take the decision, about 116-112.

So, 12 rounds, both at their best, who would win, how and why?

I think he could blast Roosy if he went for it, but more likely does the cagey stuff, gets a few kd , and wins something like 117-109

Haye by decision as well (117-111 or 116-112)
