Wallin believes that if this fight takes place, Joshua will win it.
"I'll watch that fight. It would have been great if they had fought about five years ago, but I'll still watch it now as well. I think it's still a big fight.
For Wilder and Joshua, you also have to remember that losing is not the end. People lose all the time, so they can come back and perform successfully. You should never discount them. But if this fight happens, I actually believe Joshua will win and probably knock him out," Vallin told YouTube channel Boxing News.
