Gennady Golovkin says he is happy to move down in weight to face Floyd Mayweather.
The unbeaten middleweight is willing to drop down a division and meet the world's No 1 fighter at light-middleweight (154lbs).
Mayweather, who is expected to confirm he will be facing Andre Berto on September 12, beat Manny Pacquiao at his usual welterweight (147lbs) in his last contest in May.
Look at me, I’m not big. My last couple of fights I’m 158, 159. This is possible for me
But Golovkin, who is one of the smaller middleweights (160lbs) around, says he would have no problem moving down - as long as Mayweather moves up.
"He's a great champion," he said to ESPN's SportsNation.
"Look at me, I'm not big. My last couple of fights I'm 158, 159. This is possible for me."
Mayweather (48-0-KO26) has boxed at light-middleweight before, beating Miguel Cotto and Saul Alvarez over the full 12 rounds in 2013.
Golovkin (33-0-KO30) has campaigned exclusively at middleweight and has not been taken the distance in any of his 14 WBA world title fights, with Britain's Martin Murray - who has since moved up to super-middleweight - coming closest before being stopped in the 11th round in February.
