The last round of the second glut of group fixtures finishes today. This will be the last day with a 10am fixture.
First off, it is Serbia who face Cameroon in Group H, before South Korea take on Ghana in Group G.
Then back to Group H for Brazil and Switzerland, whilst the day's action is rounded off by Cristiano Ronaldo's Portugal against Luis Suarez' Uruguay.
All of the action is live on RTÉ2 and the RTÉ Player, with 12 hours of uninterrupted coverage beginning at 9.30am.
FIFA opened proceedings against Serbia's football association after a flag which showed Kosovo as part of their country was allegedly hung in the dressing room when they faced Brazil at the World Cup, the soccer governing body said on Saturday.
The image of the flag with the message "we do not surrender" in Serbian went viral on social media when it was shared by Hajrulla Ceku, Kosovo's Minister of Culture, Youth and Sport.
To matters on the pitch, Serbia are bottom of the group after losing 2-0 to pre-tournament favourites Brazil while Cameroon's 1-0 loss to Switzerland means the African side are still seeking their first victory in the World Cup since 2002.
The match arguably gives both Cameroon and Serbia their best chances of opening their account in Qatar.
But a loss for either team - combined with a draw between Brazil and Switzerland - would prematurely bring the curtains down on their campaign, with nothing to play for but pride in their final group game on December 2.
Cameroonian Football Federation president Samuel Eto'o, the last player to score a winner for the country in the World Cup 20 years ago, predicted his team would reach the final but a five-match winless run since September says otherwise.
This is a fairly young Cameroon team with little to no World Cup experience, however.
Although they did give a good account of themselves against the Swiss, coach Rigobert Song has promised improvement.
"The mistakes that were made (against Switzerland) will not be made again in the next game," he said after the opening loss.
In Group G, South Korea were proud of their effort in the stalemate with Uruguay in their World Cup opener but would need to find the much-needed clinical edge when they face Ghana today, where both teams will be desperate for victory.
Playing at their 11th World Cup, South Korea began their campaign with a gritty 0-0 draw with Uruguay, putting on a lively display.
However, even though they created opportunities in attack, the ability to finish off chances was missing as the Asian side had no shots on target.
South Korea tend to over-rely on attacking midfielder and captain Son Heung-min , who is slowly re-adapting after a recent facial surgery and had little impact in their opening match of the tournament.
Head coach Paulo Bento was happy with the aggression showed by the team against the experienced Uruguayans and expects to see the same in their upcoming games -- against Ghana on Monday and Portugal four days later.
The Koreans are tied with Uruguay on one point in Group H, which Portugal lead after beating Ghana 3-2.
For Monday's game at the Education City Stadium in Al Rayyan, Bento will be sweating over the fitness of defender Kim Min-jae, who was struggling after picking up a knock in their opening game.
Ghana, the first African team to score at the global showpiece event in Qatar, were disappointed to suffer defeat at the first hurdle but could gain confidence from their performance against Portugal in the second half.

Ghana reached the World Cup quarter-finals in 2010 but should they suffer defeat against South Korea, they risk getting knocked out in the first round.
After a miserable showing at the Cup of Nations this year, where they were dumped out in the group stage with only one point, Ghana are hoping for a brighter run in Qatar.
"We have to win now and we are under pressure but then so are they," Ghana coach Otto Addo said of South Korea.
Captain Andre Ayew has belief in his team, saying they always come out of difficult situations.
"We need to stay calm, relax and increase our performance. We need to try and score more and concede less," the 32-year-old said.
Returning to Group H, Brazil will face Switzerland on Monday without their talisman Neymar, ruled out by an ankle injury suffered in their opening 2-0 win against Serbia at the World Cup on Thursday, but with a host of young talent to step in for him.
The five-time world champions will also be without ever-reliable full back Danilo who also sustained an ankle injury against the Serbians.
Their absences are a blow to Brazil's aspirations of winning a record-extending sixth World Cup, but they will be relying on their outstanding generation of new talent to see them through the match.
Neymar has been crucial for Brazil in the two World Cups he has played in before, in sides that have lacked the star power of generations past.
Yet recently others have begun to shine in European soccer, with the rise of youngsters like Vinicius Jr and Richarlison, arguably the two best players in their impressive win against Serbia.

Coach Tite will have plenty of options available to replace Neymar against Switzerland and thereafter, as the player fights to be fit for the knockout stages after sustaining ligament damage to a right ankle that has troubled him for years.
Real Madrid prodigy Rodrygo would be the first option if Tite decides to use the same system with four men up-front alongside Vinicius, Richarlison and Raphinha.
The versatile 21-year-old forward played in Neymar's position in three Brazil practice games in Turin in the week prior to the World Cup.
Another option would be to pair Fred with his Manchester United team mate Casemiro to strengthen the midfield and advance West Ham player Lucas Paqueta's position as a playmaker.
However, the biggest question mark is regarding Danilo's replacement, as 39-year-old veteran Dani Alves is the only right back available.
The former Barcelona man played his last game for Mexican side UNAM Pumas in September and sustained a knee injury that has been troubling him since.
Tite tested out Real Madrid centre back Eder Militao as a full back in their friendly match against Ghana, which could be another option.
Brazil are top of Group G on three points, level with the Swiss, who won their debut against Cameroon 1-0.
Finally in Group G, Portugal could qualify early for the next phase of the World Cup with a game remaining if they beat Uruguay today, a task probably much easier said than done.
Uruguay have the World Cup edge in winning the tournament twice, albeit a few generations ago, and are more than familiar with Portugal, having knocked them out of the contest in 2018 in the round of 16.
Although Cristiano Ronaldo stole the show on Thursday, setting a record by scoring in his fifth World Cup in Portugal's 3-2 win over Ghana, his team lacked inspiration and have much to do to shake off a dismal run of World Cup form since reaching the semi-finals in 2006.

Uruguay, while failing to score any goals or even record any shots on target in their opener against a gritty South Korea on Thursday, were composed, organised and like a team capable of another deep World Cup run, with veterans and neophytes combining seamlessly and moving the ball with confidence.
All five goals of Portugal's opening game came in a frenetic final 25 minutes likened by coach Fernando Santos to a storm. He said he is untroubled going into the Uruguay match because he knows what needs fixing.
"It's nothing I'm worried about because I know that my players can do better than that, but that's football," he said. "I am totally confident that they can perform much better than this."
Portugal, with a habit of going down to the wire in the World Cup group stages, may want to avoid that this time with a final match against South Korea, the team that ended Germany's title defence in 2018.
Equally, Uruguay will want to avoid defeat against Portugal so their fate can remain in the own hands in their final match against Ghana.
Uruguay have looked good since Diego Alonso took over late last year and turned things around in qualifying. He has every player available in his squad, except Barcelona's Ronald Araujo, recovering from thigh surgery.
Alonso's defence looked sturdy against South Korea and he is blessed with plenty of attacking options through Luis Suarez and Edinson Cavani - despite their age - and Liverpool's Darwin Nunez and Manchester United's Facundo Pellistri, who looked dangerous on their World Cup debuts.
Alonso expects a tough game on Monday and for the group to be decided in the final match.
"Obviously the second game is key as is the third," he said. "Whether we qualify or not depends on us."
