Here we go again ...
Conor McGregor sounds like he's still VERY serious about squaring off with Floyd Mayweather -- telling TMZ Sports, "I told you I'm ready for that fight!"
Conor dropped Floyd's name at the UFC 205 media event earlier this week -- saying he might need to set up a bout with the boxing legend after he runs through all the big names in the UFC.
Of course, Conor and Floyd tried to get this thing going earlier this year, but it fizzled out.
We spoke with Floyd on Tuesday and he told us there's still a chance the two will get it on ... but hinted that it's all about getting the money right.
Fingers crossed ...
