The World Cup will start on Monday, and given that you are not familiar with the schedule, here we have compiled a guide for fans about the first round of matchdays, please pay attention to checking.
A组
Qatar vs Ecuador, 21 November at 00:00, Senegal vs Netherlands, 22 November at 21:00
On the first matchday, injuries prevented Senegalese striker Samane from meeting the Netherlands where former Liverpool team-mate Van Dijk is based.
Senegal are the new champions of the Africa Cup of Nations, while the Netherlands are unbeaten in their last 15 matches since losing 2-0 to the Czech Republic in June last year.
In the opening match, the hosts Qatar will play the first World Cup match in their football history, and they will play Ecuador with a completely domestic-based team, Ecuador is stronger on paper, as evidenced by the team rankings, the value of the players and the team's heritage.
Group B
England vs Iran, 00:00 on 21 November, USA vs Wales, 03:00 on 22 November
England face a team in excellent form and Iran are unbeaten in their last three friendlies, including a win over Uruguay and a draw with Senegal, in stark contrast to the Three Lions' six-game winless run.
Wales are competing in the tournament for the first time since 1958, while their opponents missed the World Cup in 2018, but they have competed in seven World Cups and have qualified four times in the group stage, including in 2010 and 2014.
Group C
Argentina vs Saudi Arabia, 22 November at 18:00, Mexico vs Poland, 23 November at 00:00
Argentina are among the favourites to win this tournament, and against Saudi Arabia, which consists entirely of domestic players (with only three players with overseas experience), it is not a big deal to believe Argentina will get off to a good start.
Mexico was evenly matched against Poland, with Martino's side ranked 13th in FIFA and their opponents 26th, and Mexico have secured group qualification in the last eight World Cups.
Poland has not done so since 1986.
Group D
Denmark vs Tunisia, 22 November at 21:00, France vs Australia, 23 November at 03:00
Notably, three teams in this group were also drawn in the same group at the 2018 World Cup, with Tunisia replacing Peru four years ago.
France and Australia also met in their opening match, with the Gallic Roosters winning 2-1 and eventually winning the title.
Denmark advanced to the knockout stage along with France, as they have done in the last five World Cups (only 1 time without qualifying). Tunisia are playing in the World Cup for the sixth time, but they have never made it to the group stage.
Group E
Germany vs Japan, 23 November at 21:00, Spain vs Costa Rica, 24 November at 00:00
The "Asian team" may be Germany's bitter master, and this time, they must reverse the fortunes of 2018. Four years ago, Germany finished bottom of the group after losing to South Korea and was ruthlessly eliminated. Japan, on the other hand, reached the round of 16 last time.
When Spain plays against Costa Rica, their youth army has to step up. This time, Spain has five under-21 players, the most in this World Cup, who are a youth janissary.
Group F
Morocco vs Croatia, 23 November at 18:00, Belgium vs Canada, 24 November 03:00
Croatia will definitely want to emulate their impressive performance in 2018, when they finished runner-up in the cup.
Canada have not played in the World Cup since 1986, when they lost all three of their group stage games without scoring a goal, and their opening match against FIFA's world number two Belgium may not have been a good signing.
Group G
Switzerland vs Cameroon, 81:00 on 24 November, Brazil vs Serbia, 03:00 on 25 November
Cameroon have played in the World Cup five times since reaching the semi-finals in 1990, but they have never qualified in the group stage.
Meanwhile, rival Switzerland also played in five World Cups and qualified four times during this period.
Brazil are favourites and they will rely on the team's big-name players to make that happen. Brazil have been on their way to the table this year, currently undefeated in all competitions, with their last appearance before the World Cup on September 28, beating Tunisia 5-1. Notably, they did not choose to play in the warm-up match before the World Cup.
Group H
Uruguay vs South Korea, 24 November at 21:00, Portugal vs Ghana, 25 November at 00:00
At the 2018 World Cup, Uruguay qualified in all three group games and reached the quarterfinals. In the 2010 World Cup, they finished fourth in the cup and impressed the fans.
The rival South Korea has as many as 12 players over the age of 30, which is more than any other country.
In contrast, Ghana has the youngest squad in this World Cup tournament as they face Portugal, which has never crossed the round of 16 since reaching the semi-finals in 2006.
