Should STFU and be thankful Frankie even knows who he is - at least enough to have accepted a fight with him in the first place.
Comes across as pretty entitled and utterly narcissistic. The whole post is a thinly veiled ‘What about me?’ tirade. Did it ever occur to him that Zombie is a well respected, dangerous martial artist in his own right and perhaps Frankie has long had a desire to fight him? They have been scheduled previously in the not too distant past, if I remember correctly.
Get one thing straight, Frankie doesn’t owe him a fucking thing and is free to liaise with the UFC as is deemed necessary.
