The Young Bucks have updated their Twitter bio recently to the following:
"One day we’ll wrestle New Day & everyone will rejoice. Remember this bio."
This is the same sentence structure they used to tease that they wanted to wrestle The Revival. That was several years before it actually happened when they came to AEW as FTR.
Young Bucks have previously called out New Day (as well as The Revival and Hardy Boyz) during a NJPW promo.
