If Chile ends up facing Bolivia in its Copa America semifinal it will be a very different match from its group game where it won 5-0, coach Jorge Sampaoli said on Wednesday.

"We beat Bolivia when both teams had already qualified (for the knockout stages)," Sampaoli said after his side beat Uruguay to seal a place in the final four.

"If Bolivia goes through it won't be the same match."

Bolivia faces Peru in the southern Chilean city of Temuco on Thursday. The winner will play the host in Santiago next week for a berth in the final.

Peru has always had good players, Sampaoli said, praising its Argentine coach Ricardo Gareca for the way he guided the side through a tricky Group C.

"When you see them competing against teams like Brazil, Colombia and Venezuela you realize that Peruvian football is as good as any," he said.

"And Ricardo has improved the performance of some of their players significantly."
