Mexico pulled off a shocking upset when it beat defending champions Germany, 1-0, in its opening match of the 2018 World Cup. Now, Mexico faces South Korea on Saturday at 11:00 a.m. ET. These two countries have met one time at the World Cup before, with Mexico winning 3-1 in 1998. Mexico enters this match as a -160 favorite on the money line, meaning you'd need to wager $160 on a Mexico victory to win $100. South Korea is +500 (risk $100 to win $500), while a draw is +275. The Over-Under on total goals is 2. Mexico has 25-1 World Cup odds to win it all, while South Korea is 1,000-1.

Before you lock in your 2018 World Cup picks, you need to see what European football expert David Sumpter has to say.

Sumpter is an applied mathematician who wrote "Soccermatics," a book that explains how math works inside the sport. Together with other experienced analysts, Sumpter developed the powerful Soccerbot model.

The Soccerbot reads current odds and all team performance data, calculates key metrics and predicts upcoming matches. In nearly three seasons since its inception, the Soccerbot is up an incredible 1,800 percent against closing sportsbook odds.

Following Sumpter has paid off so far at the World Cup 2018. The model nailed the Argentina-Iceland draw at +385, the Brazil-Switzerland draw at +360, Iran (+275) over Morocco, and Senegal (+220) over Poland, just to name a few.

Now the Soccerbot has digested the film, crunched the numbers and broken down every single player on Mexico and South Korea. The model has released a very strong money line pick, which it's sharing over at SportsLine.

The model knows Mexico is looking to use the momentum from a 1-0 win over Germany to carry it on Saturday. Three more points Saturday clinches a spot in the 2018 World Cup knockout stage.

Mexico's Guillermo Ochoa was masterful in the net, becoming the only goalie ever to shut out both Germany and Brazil at the World Cup.

Meanwhile, South Korea will look to secure a positive result against Mexico after losing to Sweden 1-0 in its opening match. South Korea has now lost three consecutive World Cup matches and is winless in its last seven World Cup games overall. Its woes can be attributed to its defense, which has failed to keep a clean sheet in 12 of its last 13 World Cup fixtures.

South Korea's offense isn't doing the defense any favors, either. The Koreans have failed to score in their last two games and will need to put one in the back of the net to have a shot against El Tri.

So which hungry nation wins Saturday? Or does it end in a draw? Visit SportsLine now to see the strong Mexico-South Korea money-line pick, all from a European football expert whose powerful model is up 1,800 percent in less than three years.
