Solano: Politics and football don't mix
"This match is important for lots of reasons as a win could get us back on our feet in the qualifiers," Peruvian media quoted him as saying on Wednesday.
"But this is football, enough talking about other things.
"We shouldn't mix politics and football, our countries are brothers and the time of war is over.
"This is a special match, it's always been seen as a 'clasico' and we hope we can get the three points."
Relations between the countries have been periodically rocky since the War of the Pacific from 1879-1883 and last week Peru formally presented its arguments on a bitter maritime border dispute at the International Court of Justice in The Hague.
Peru, bottom of the 10-team South American group with seven points from 10 games, have promised tight security for Sunday's match at the Monumental.
Chile, enjoying a revival under Argentine coach Marcelo Bielsa, are fourth with 16 points.
