I think it is not quite fair with this fight. If we are facing a two different athlete with different sports on their field this is quite uncomfortable to them well Manny will not fight to McGreggor in this Octagon, BUT if we see this in vice versa what if McGreggor vs Pacquiao in a boxing ring it's a good thing still this is impossible unless they will release a large amount of money. AFAIK for this upcoming match of Senator Manny, he is going to retire its been a long year he is fighting to the Filipino Pride I think this is the time he will give the spotlight to Donaire.
McGregor wanted this fight. That just means that he is aware of the match being unfair which supports the fact that he is not just after this fight but after the fact that this match will generate millions and millions of money. In terms of retirement, I don't think this will be his last one. There are a lot of times that people are talking about retirement but Manny is just looking at what he can do as long as he's still kicking.
