IN what Mondelez International says is its largest investment ever in a multibrand marketing effort, the snack-food giant on Wednesday will announce an expansive sponsorship deal with American soccer teams and players.

In a three-year deal that begins in 2014, Mondelez products will become the official snacks of the women’s and men’s United States national soccer teams. Mondelez also will be the official snacks in the United States for Club Deportivo Guadalajara, a team in Mexico commonly known as Chivas, meaning that the company will sponsor the occasional matches the team plays in the United States.

Mondelez is also making sponsorship deals with two Major League Soccer players, Clint Dempsey of the Seattle Sounders and Omar Gonzalez of the Los Angeles Galaxy, signing both for one year. Alex Morgan, an Olympic gold medalist who plays for the Portland Thorns in the National Women’s Soccer League, signed a three-year deal with the brand.

Its agreements with the national teams, Club Deportivo Guadalajara and the players call for it to be an exclusive sponsor in all four of its snack categories, meaning its brands will be their official cookie, cracker, candy and gum.
