Floyd Mayweather Jnr backed a more popular boxer

Floyd Mayweather Snr has claimed that age is beginning to catch up with his former world champion son, Floyd Mayweather Jnr.

The American's father has admitted that the 35-year-old is starting to show signs of a possible decline but insists that he is still more popular than his rival Manny Pacquiao.

Mayweather Snr told ON The Ropes: "It's been proven already that my son can sell more tickets than Pacquiao! It's been proven that on a couple of different occasions that my son can sell more tickets than Pacquiao.

"Age might be catching up with him [Mayweather Jnr] now. I'm pretty sure it's catching up with him. He's not Superman.

"Even though he keeps his body and stuff in good shape, you know I'm pretty sure that's going to have a big thing to do with it too."

Mayweather Jnr revealed this week that a potential fight with Pacquiao is unlikely to take place this year.
