The comments have whipped up the hype prior to the Chelsea re-match, although Morientes will not be able to have any input over the result, after a hamstring strain put him out of the match.
"If I was a betting man I'd tip us and Real Betis to go through - and not Chelsea. We've got them sussed," Nando said.
He added, "We were accused of being lucky in the semi-final. Yet Chelsea did not score in either leg and that tells you a lot about the good work done by Rafa Benitez. It was a perfectly-planned match.
"We have a great chance of beating them again - not because we are European champions but because we know how to play Chelsea. Perhaps it is better for us to face Chelsea because we know them so well."
