Floyd Mayweather has called out UFC star Conor McGregor once again, telling the lightweight champion he should "sign the paper" if he wants to make the proposed superfight between the two happen.
As reported by ESPN's Ben Dirs, the 40-year-old made the comments during his tour of the United Kingdom, saying: "If Conor McGregor really wants this fight to happen, stop blowing smoke up everybody's ass. Sign the paper. Sign the paper. You said you were boss, so just sign the paper and let's make it happen."

The two have been trading shots in the media for some time now, as rumours of a potential superfight between the duo have persisted since Money last fought in 2015.
