Costa Rica vs. Serbia
Group E, Samara Arena, Samara
The jostling for position behind Brazil in Group E begins Sunday, when the darlings of the 2014 World Cup take on an intriguing Serbian side. Costa Rica returns most of the group that toppled England, Italy and Uruguay in a surprising run four years ago that ended with a loss to the Netherlands on penalty kicks, but Los Ticos will be playing under pressure this time around. Costa Rica is experienced but aging, and this summer is thought to be its last big chance to break through with this talented group.
