That was a great match. The first one was also a great match. There is no reason to deprive MMA fans of another great match in a second UFC rematch. Both fighters deserve it also.
If only Pereira survived those counterblows, this could have easily been a repeat of their first match. But Pereira was also the one who got saved by the bell in their first fight. A third fight is needed.
I can say that the two of them have an eternal rivalry, apart from that Israel's Adesanya uses the "mocking" celebration that Pereira's son did to him first. really entertaining
The fight could end with either of them winning via knockout. They both have the power. So the knockout win could come from Adesanya or Pereira. They're also very eager to prove something.
Although I really want to see a tie breaker, it seems the interest to have a rematch is very low. Dana White is not interested. Even Pereira himself is not interested anymore. Adesanya has also declared that he is not anymore interested in facing Pereira once more. So the rivalry is not eternal. It has already ended.
