Well this looks promising

"We are really glad that Anthony Joshua said for the first time 'I will fight Deontay next...' and we believe he is a man of his word. Deontay accepts the challenge," his manager Shirley Winkle told the Daily Telegraph .
"We want to make it public that Deontay wants the fight, and we are prepared to come over, or meet here and get the deal done. Deontay is ready to sign and come to the UK to fight this summer."
