Stoke-On-Trent-born Blackburn star Brereton linked up with Eduardo Vargas for Chile's 10th-minute winner in only his second appearance and first start for his adopted country on Friday.
The 22-year-old, who has a Chilean mother and grandfather, was a surprise call-up for the Copa America but has not disappointed, earning praise from head coach Martin Lasarte.
"It must be very difficult for him to play for a national team where they don't speak the language he speaks," Lasarte said during his post-match news conference following the Bolivia win.
"He is making a great effort and the group is helping him adapt. He had his chance, his goal, he shouted out and he scored."
Brereton finished the match with 18 successful passes out of 20 attempted (90 per cent), three shots on target, one chance created and having scored the winner.
