World Cup 2022: What to expect on Day 5

And so the first round of games will be completed today, with World Cup favourites Brazil taking on Serbia, while Cristiano Ronaldo, currently without a club, is set to make his fifth appearance at the finals as Portugal face Ghana.

Taking a glance across today's four games, you would have to say that there's an appeal to each of them.

Switzerland, now regular attendees at major finals, face a Cameroon side that has struggled for form of late.

A genuine contender, in the shape of Uruguay, meet South Korea, the nation that made it all the way to the semi-finals on their home patch in 2002.

A week after he sat down for a chat with Piers Morgan, Ronaldo, now no longer on the books at Manchester United, will be hoping that his talking on the pitch does the business.

Ghana did knock out Nigeria to reach a fourth finals, but their form since has been patchy.

Brazil will be wary against the Serbs, the latter topped Ireland's group in qualifying courtesy of a last-gasp win against the Portuguese on the final day.

All of the action is live on RTÉ2 and the RTÉ Player, with 12 hours of uninterrupted coverage beginning at 9.30am.

After beating France and then taking Spain to spot kicks at Euro 2020, Switzerland provided further evidence that they are now a force to be reckoned with. In qualifying, they held off Italy to claim top spot.

Former player Murat Yakin took over as coach from Vladimir Petkovic after the Euros and hasn't altered their style of play too much.

There is much experience in their squad, with goalkeeper Yann Sommer, captain Granit Xhaka, now back to his best with Arsenal, Ricardo Rodriguez, Haris Seferovic and Remo Freuler, one of the many who arrived at Nottingham Forest during the summer, forming a strong spine.
