The four teams chasing unbeaten Brazil will be in action Sunday when the 2021 Copa America continues with two Group B matches. It has been a low-scoring tournament so far, and these four teams have combined for one goal and one victory. Brazil has seven of the 15 goals scored by the 10 teams across all 14 games at the Copa America 2021 and sits atop Group B. Ecuador lost 1-0 to Colombia and Peru was blasted 4-0 by Brazil in their only games so far. Colombia, one of the favorites to advance, also has a scoreless draw against Venezuela, while the Venezuelans suffered a 3-0 setback to Brazil in their opener.

Venezuela and Ecuador square off at 5 p.m. ET, while Colombia takes on Peru at 8 p.m. ET. William Hill Sportsbook lists Colombia as the -154 money-line favorite (risk $154 to win $100) in its Colombia vs. Peru odds. The 2021 Copa America odds at William Hill also have Ecuador as the -150 favorite, with over-under for total goals scored at 2.5 for both games.

Top Copa America 2021 predictions for Sunday, June 20

For Sunday's games, Fornelli's picks don't include Ecuador winning, even though it is a strong -150 favorite against Venezuela. The Venezuelans have had a long list of players out with positive coronavirus tests, but they still battled to a scoreless draw with Colombia on Thursday. That same Colombia team beat Ecuador 1-0 in Sunday's opening match. The series has produced plenty of draws, with Ecuador holding a 16-5-11 edge. The last match, a June 2019 friendly, ended in a 1-1 draw.

Venezuela is the 30th-ranked team in the world, 23 spots ahead of Ecuador, and its depleted state is a big reason it is an underdog. It needed to call up 15 players to cover as players were forced to quarantine, but it has been resilient and knows it needs points to stay in the race to advance. Ecuador could certainly win the match, but Fornelli is offering another strong pick on this game as part of his Copa America 2021 parlay.
