"Messi - he's more normal. But Cristiano is more focused. That's why I choose Cristiano," Prochazka said.
Prochazka is already scheduled to rematch Alex Pereira, the promotion's bantamweight champion, on June 29. Their confrontation will headline the 303rd UFC tournament, which will be held in Las Vegas.
Recall that in the first fight, Pereira won early against Prochazka, finishing him in the second round.
