A week after defending his UFC light heavyweight title against Anthony Johnson, Daniel Cormier has taken part in yet another ferocious fight.
This time the battle involved exchanging Twitter blows with long-time rival Jimi Manuwa.
The number three ranked fighter was ringside when Cormier defeated Johnson last week, and immediately insisted he should be the next man up to face the title-holder.
Now Manuwa has taken it a step further.
Check out their fiery exchange below:
With UFC president Dana White hesitant to match Cormier with Jon Jones, who is returning from a drugs suspension, this fight looks like a near certainty.
Who do you think will win it?
