Peru striker Paolo Guerrero says goals in successive games at the Copa America have whetted his appetite and now he can't wait to bag another against neighbouring Chile.
The Hamburg striker's effort against Mexico took Peru to the brink of the quarter-finals, adding to his earlier goal that secured a useful draw with Uruguay to spark belief that the Blanquirroja could be on the way back after some lean years.
They have not won the South American championship for 36 years and endured an abysmal World Cup qualifying campaign to miss out on the South Africa finals but Guerrero says confidence is rising fast.
"Now we are really motivated to beat Chile -- and we are optimistic," said the 27-year-old, who is nicknamed the warrior and who has spent most of his career in the Bundesliga, first with Bayern Munich then Hamburg.
Guerrero's only worry is that the team were highly profligate in attack, missing several good chances against the Mexicans.
"We missed too many oportunities -- I had at least four -- and we should have won by a greater margin. We know against Chile it will be tough, but there is a lot of quality in this team."
With Chile also starting well in beating the Mexicans and drawing with Uruguay, both neighbours are set fair for the last eight and Tuesday's Pacific clasico in Mendoza will decide who tops the group.
