Next up in our 2018 FIFA World Cup preview is Group E, in which Brazil's final 23-man squad made the headlines after several big stars were snubbed.
Click through the gallery above to see the biggest stars who were snubbed for Brazil's Russia 2018 squad.
Group E kicks off on Sunday, with Costa Rica against Serbia at 14:00, and the Selecao and Switzerland locking horns at 20:00.
Brazil have lost only one of their 21 games under coach Tite, conceding just five goals throughout this run leading up to the World Cup. Switzerland, meanwhile, have also been in good form as they, too, were defeated only once in their past 17 games, even though they had to go through the European play-off qualifiers to book their ticket to Russia.
Serbia lost only one of their 10 games during the qualifiers, but have since been defeated twice in six preparations games, while Costa Rica's form has been horrible leading up to the tournament. The team, built around Real Madrid goalkeeper Keylor Navas, have only won two of their last 10 matches.
Selecao coach Tite's squad announcement made the headlines with players such as Alex Sandro and Fabinho being left out, but superstar Neymar has returned to fitness in time, and scored in both of Brazil's final two friendlies.
First round of fixtures:
17 June, 14:00 – Costa Rica vs Serbia, Cosmos Arena
17 June, 20:00 – Brazil vs Switzerland, Rostov Arena
