Asked if Fulham can win the tournament, Zamora said: "I can't see why not.
"If we can keep the away legs tight, I think we've got a chance against anybody at home."
With England boss Fabio Capello watching from the stands, Zamora began the fightback with a fine goal after sending Fabio Cannavaro sprawling.
And the hitman was clearly delighted following another impressive display.
He added: "It was a massive game for myself and the club.
"We believed we could do it and we're delighted with the result.
"It's a massive scalp and we're over the moon."
