Young Brazilian Luana Silva says she was overwhelmed to defeat one of her idols, Australian Stephanie Gilmore, at Bells Beach.Gilmore's World Surf League (WSL) return as a full-time competitor started on the wrong note on Saturday.Silva eliminated the eight-time world surfing champion in the first round.Gilmore, a four-time winner at Bells Beach, had previously never finished worse than the quarterfinals.Silva led throughout their heat in the four- to six-feet conditions, scoring 11.83 to 6.10.Gilmore, 38, is competing in the World Surf League as a wildcard after a two-year sabbatical from full-time competition.Silva was runner-up to Australian Isabella Nichols at Bells Beach last year.She said Gilmore helped inspire her to become a professional surfer."I don't think I could have had a harder match-up … she's the 'GOAT'," Silva said."She had more to lose than I did, but at the same time, these last two years, I actually got her spot when she wanted to take the break."So it's like, 'Thanks Steph, I can't be your friend in the water'."But I'm stoked I have the most respect for her — she's just the GOAT, I love her.''Silva said she focused on her own surfing but admitted to being in awe of Gilmore as they went head-to-head."When I paddled out there, it was such a 'pinch-me' moment
