The Brazilians agonisingly lost 3-2 to Egyptian Premier League side Pyramids in last season's final.
They currently hold a 1-0 advantage heading into their semi-final second leg against Esperance at Loftus Versfeld on Saturday.
Having overcome the Tunisian team over two legs in last term's quarter-finals, Cupido is confident of a win at home to reach a final encounter against one of AS FAR Rabat or RS Berkane.
When quizzed about the differences over the two campaigns, the player said on iDiski Times: "I don't think there's much of a difference, we started bad last season as well – but as a team we're growing together, we starting to believe it's possible and I don't think there's much difference.
"It's just the self belief in the players, the coach gives us belief as well, to know that we can reach the final again."
On his dreams of winning the whole competition, the player added: "I think it's very big for any player in the country to win the Champions League, everyone dreams of winning the Champions League and playing for a big team like Sundowns, it's a really huge opportunity for each and every one of us.
“It's actually a chance for everyone to show our qualities also, and last season we were very close, this season we have another opportunity and we learn from last season going into this second leg semi-final as well.”
