Top World Cup picks for Monday
- Argentina vs. Austria: Argentina to win (-230)
- France vs. Iraq: Over 3.5 goals (-106)
- Norway vs. Senegal: Erling Haaland to score (+115)
Argentina vs. Austria: Argentina (-230)
"Argentina should be full of confidence after cruising to a 3-0 win against Algeria in their opening World Cup game," Green told SportsLine. "The reigning world champions dominated that game, and Lionel Messi's hat-trick was the highlight of the tournament so far. La Albiceleste should extend their winning streak when they face Austria. The Austrians beat Jordan 3-1 on Matchday 1, but they could struggle to deal with Argentina's sheer firepower. Even if Messi isn't firing on all cylinders, they can call upon Lautaro Martínez and Júlian Álvarez, so they should win this game."
France vs. Iraq: Over 3.5 goals (-106)
"France dismantled Senegal in the last 30 minutes of their opening match that saw France score three goals past the 65th minute," Eimer pointed out. "Kylian Mbappe found his form picking up a brace, while Bradley Barcola snagged a goal off the bench. Michael Olise was pure class in his play both on and off the ball, and all around France looked like they were living up to their name as tournament favorites. Senegal has a significantly better defense than Iraq, which means they could be in for a rough time. France will not only want to win this match, but will want to run up the score as well to build up a hearty goal differential, knowing that Norway is also scoring freely."
Norway vs. Senegal: Erling Haaland to score (+115)
"Haaland is a superstar, with multiple Premier League titles and Golden Boots under his belt, and he always delivers for his country," Green said. "He has now scored an obscene 57 goals in 51 games for Norway."
