Dustin Poirier has used one of Nate Diaz 's most famous call-outs to push for a fight with the UFC fan favourite.
Poirier and Diaz verbally agreed to a fight last month just days after 'The Diamond' missed out on the UFC lightweight title against Charles Oliveira.
The promotion gave the fight the go-ahead, with UFC 270 in California or UFC 271 in Texas being potential venues for the welterweight clash.
