Floyd Mayweather wants a fight with rival Manny Pacquiao after beating Miguel Cotto on Saturday night.
Mayweather beat Cotto on points in a tough fight in Las Vegas, and speaking afterwards insisted he wanted Pacquiao next.
"I tried to make the Pacquiao fight and that didn't work, so I fought Miguel Cotto instead and gave the fans a great fight," said Mayweather.
"I want to fight Pacquiao but he has to take the test, and I'll fight him."
The 35-year-old found himself on the back foot on a number of occasions during Saturday's pay-per-view showdown, with Cotto landing numerous left hooks.
The constant pressure was clearly taking its toll on 'Money' in the middle rounds, but Mayweather got the decision victory, largely due to a change in style in the latter stages of the fight.
Afterwards, Mayweather paid a glowing tribute to his opponent.
"You're a hell of a champion. You're the toughest guy I ever fought," he said.
"You want to give the fans what they pay for and that's excitement. It comes with the territory when you fight a future Hall of Famer like Miguel Cotto.
"I had to fight hard and suck it up. I dug down and fought him back."
Cotto believed he did all he could to win the fight.
"The judges said I lost the fight. I can't do anything else," he said.
"I have to take my defeat.
"He knows what kind of fight Miguel Cotto brings, and so do the fans. I'm happy with my fight and with my performance and so is my family. I can't ask for anything else."
