Deontay Wilder has challenged Anthony Joshua to head Stateside to defend his IBF heavyweight title.
The 26-year-old remained patient to overcome Dominic Breazeale on Saturday evening, retaining his belt with a seventh-round stoppage at London's O2 Arena.
Having now claimed his 17th professional victory, the next mandatory challenger for Joshua is Joseph Parker, but Wilder has urged promoter Eddie Hearn to weigh up a fight in the United States.
Wilder took to Twitter to say: "Since the winter time you planned on @Tyson_Fury. Hey it's time to make your American debut @anthonyfjoshua. Eddie Hearn said sooner than later so let's make sooner "NOW"!!!!!"
WBC heavyweight champion Wilder will defend his title against Chris Arreola in Alabama next month - his fourth defence in six months.
