The National Women's Soccer League Challenge Cup starts June 27 with nine teams vying for the trophy. Before you bet this exciting event, you NEED to see what our proprietary European soccer model has to say.

Created by two Norwegians -- professional poker player and sports bettor Jonas Gjelstad, and economics and engineering expert Marius Norheim -- the model analyzes worldwide betting data and exploits market inefficiencies, helping its followers cash in. Over the last three years, their algorithm is up an eye-popping 13,800 percent!

Now, the model has broken down the NWSL Challenge Cup odds and is highly confident it has the winner. We can tell you the model is fading the Chicago Red Stars, even though they're second-favorites at 3-1. "They just lost their top scorer Sam Kerr to Chelsea," Norheim told SportsLine. "Time will tell whether Yuki Nagasato will step up to fill her shoes in terms of goal scoring."

The model also loves a double-digit long shot that is "by far the best value pick," saying this underrated team should be priced at much lower odds. You ABSOLUTELY need to see the model's picks before you bet.

So who wins the NWSL Challenge Cup? And which long shot could stun the soccer world? ... Join SportsLine now to see all of the model's picks for the NWSL Challenge Cup, all from the proprietary European soccer model that's up an eye-popping 13,800 percent!
