I know its normal for some boxer to trashtalk because it can trigger your opponent to challenge you and see whose stronger but I dont like this behavior of Casimero.
Anyway their first scheduled fight were postponed last April so hopefully this will happen soon. Since like what the article stated, Casimero is willing to go to Inoue's territory just to fight him.
The thing is that we don't know if they're already communicating and setting this match as soon as possible.
They can schedule the fight by December, I'm sure Casimero had already had some rest now, and they can also start training as soon as the contract is signed. It's open to the public that Inoue wanted to have this fight this year, but until there's no contract signed, we can't assure we will see it this year.
For me the fight should happen next year, whether in US or in Inoue's Japan.
I agree that they need to rest first, one fight a year will be good enough. Besides although fans are still allowed to watch the fight live, it's better to happen in 2022 as more people have been vaccinated by then. And maybe they need to work out the terms of the fight and there could be a lot of back and forth changes
Some fighters can have 3 fights in one year.
Liked Canelo Alvarez will have his 3rd fight this year with Caleb Plant. https://boxrec.com/en/proboxer/348759
While Casimero and Inoue only had one fight this year so far, I think they are still good for the last one which could be scheduled in the last month of the year. I think Inoue should have not said that he wants to fight Casimero this year if he is not serious with that.
