Weld was behind the only previous European success in Australia's biggest horse race, when Vintage Crop triumphed in 1993.

And the 54-year-old succeeded Down Under again when Media Puzzle claimed a two-length win, with stable companion Vinnie Roe a brave fourth under top weight.

"It was a wonderful feeling, a very proud moment. Our plan operated perfectly," he said.

The win earned Media Puzzle's connections A$2.4 million (�830,000).

"Vinnie Roe has run a wonderful race. He hasn't let us down on a track that was too firm for him. He'll be back," Weld added.

The trainer reflected on his desire to add to his enviable Cup record in the 3,200-metres handicap.

"I always said I would come back for the Melbourne Cup when I had the right horse," Weld said.

"Time flies. The last year Vintage Crop ran I thought it was his best ever performance. He was a nine-year-old and he gave his all.

"Two years ago (when fourth in the English St Leger) I said Media Puzzle would win a Melbourne Cup.

"In fact, he then had an unfortunate fracture and broke his pelvis and stood in a box for four and half months. He's fought all the way back for us.

"Media Puzzle adores this country and so do I. What a great day for Ireland."

Weld paid tribute to the winning jockey amid emotional scenes.

Damien Oliver steered Media Puzzle to victory just a week after the jockey's brother Jason died in a riding accident.

"It's a wonderful moment for Damien Oliver. I'm so proud of him," said the trainer.

Oliver, who also rode Doriemus to victory in the 1995 Cup, said: "Dermot Weld is truly one of the greatest trainers in the world."
