Realistically who should fight Mayweather in his final fight in September?

[Cobra_]

You can't get a better opponent than Pac but now he choose to fight him before retirement who ever he chooses will disappoint unless they have a rematch I guess.

Is there anyone he could even fight in his final fight in September that wouldn't disappoint?

[BOXEO _]

He should try to avenge his defeat and fight Pacquiao in September.

If he's not interested in that I'd like to see Cotto/Mayweather 2.

He should try to avenge his defeat and fight Pacquiao in September.

I assume most will say rematch but lets say he wins a wide UD for the sake of discussion.

[Pain~Lucy]

He's getting retired by Manny, come May 2

[George Orwell]

avenging his defeat to Pacquiao obviously

[Build That Wall]

Danny Garcia for win 49.

[Pigeons]

Cotto for the lineal MW title. I don't think it will be his last fight though.

[Reloaded]

He will beat Manny in May and then fight Cotto for the MW title .

Mauricio Herrera

I assume most will say rematch but lets say he wins a wide UD for the sake of discussion.

I'd like to see Cotto/Mayweather 2 more than anything else.
