David Trezeguet insists Hercules can pull off an upset against Barcelona.
The former Juventus star knows the size of the challenge facing the men from Alicante.
The 32-year-old said: "Barcelona are the best team in Europe at present, but we will stick to our guns, and are eager to make this a good match. We all know that this will be a very delicate game for us, but at the same time we have nothing to lose and everything to gain.
"We will look to strike a blow. We will have the opportunity to make history if we pull off a great coup."
