The Latino fighters needed translators after their fights. Pac is really not that good in English when he started fighting in the US. What I want to say is that mastery of the English language is not a prerequisite to make it big in the US. Let their fights do the marketing for them. If they are exciting and beating the elites of their division, then mainstream media and casual fans will eventually notice them.
Korobov is another straight up European. I've seen a few of his pro fights and don't see anything special. Golovkin is better.
Numerous latinos live in the states,hmi! Of course the knowledge of english is not the most important factor when trying to sell a certain fighter to the American public. Your name,your passport,your ethnic background,your family ties,and so on and so on. I am still surprised that Lyakhovich is A merican based by the way. He stems from Belarus which is considered to be a rogue state by the USA,couldnt speak English very well when he moved over to the USA,and so on and so on. Miracles happen:happy
I'm pretty impressed with him. Seen him fight twice now. If he can keep his head right he can be special.
