I wonder if this is an exhibition match, and therefore to a greater extent a contractual match, then how in this case you can bet on it, because this is manipulation and insider in its purest form and relying on Pacquiao's skill here is very reckless.
It's very obvious that bookies will not list this fight due to the fact that it's an exhibition match and there's no flame between the participants.
If ever you will see bookies that will cover this match, then think twice before placing your bet as it might play you instead.
Besides, why place a bet on exhibition matches where there are thousands of other options to place your bet.
And it is not difficult to understand why bookies do not like offering exhibition matches, this is because there is not really any reason for each side to pursue victory with everything they have, if Manny were to lose no one will hold it against him as we know he is retired already, and in the case of Yoo I doubt anyone cares, so with those kind of conditions giving odds for a match like that does not really make any sense from the point of view of the bookies.
