Santiago: Gary Medel, Jorge Valdivia and Eduardo Vargas are three Chile players who have caught Sergio Aguero`s eye at the Copa America, the Argentina striker said on Friday.
"I think Medel is crucial in defence and Valdivia is aplayer who can create things in midfield," Aguero told a news conference ahead of Saturday`s final between the two sides.
"Vargas is on form and can create a goal out of nothing at any moment. He`s a player who maybe doesn`t get that many touches of the ball but he`s always there so you have to be careful.
"Chile have some great players ... they have a great team," added the Manchester City marksman.
Medel may hold the key as Chile try to stop Aguero and attacking partner Lionel Messi.
Valdivia has been the host nation`s most inventive midfielder in the tournament while Vargas has scored four of their 13 goals including a double in the 2-1 defeat of Peru in the semi-finals.
Aguero has bagged three of Argentina`s 10 goals and is their top scorer in the competition.
