Boxing fans is still downgrading Joshua's capability, he is capable of knocking out anybody and he has improve a lot since losing to Ruiz, this is going to be a psychological fight, both are capable of dominating a fight my favorite to win here is Tyson but I don't rule out the possibility that Joshua can beat Fury, he is capable and he always can if the opportunity presents itself.
Yes, of course, Joshua is capable of beating anyone in the division including Fury.
But boxing fans including boxers predicts that Fury will beat Joshua. Because Fury is very technical boxer and also a heavy puncher. That two reasons alone makes it hard for Joshua to overcome, but Fury is the taller guy as well.
And then we have seen the Fury has a granite chin, although broken by Wilder, he was able to "weather the storm", get up and finished the first first. Sadly, he was rob but he dismantled Wilder in the rematch. It's going to be a long shot for Joshua to beat Fury, in my personal opinion.
