Peru, dreaming of a first triumph in 36 years, will try to halt a resurgent Colombia on Saturday in their Copa America quarter final meeting.
"Now we have Colombia. A tall order but but we have to have faith we can get past them. Go Peru," said Peruvian striker Paolo Guerrero, who plays his club football with Hamburg, on his Twitter account as Sergio Markarian's Blanquirroja target a shock.
Recent meetings between the two have been tight affairs - they parted 1-1 in a Bogota friendly last November and World Cup qualifiers ended 1-0 to the Colombians on their home patch and 1-1 in Peru.
