Belgium, Germany and Croatia being their tournament campaigns today.
Olivier Giroud last night equalled Thierry Henry's goalscoring record with France.
The AC Milan striker brought his total to 51 with a brace in France's 4-1 win over Australia in Group D at the World Cup.
Kylian Mbappe and Adrien Rabiot scored the others as France began their World Cup defence in style.
Next up for them is a meeting with Denmark in Doha on Saturday afternoon.
Elsewhere yesterday, the Danes drew nil-nil with Tunisia, while Argentina suffered a shock 2-1 defeat to Saudi Arabia in Group C.
The other game in that Group was a goalless draw between Mexico and Poland.
Attention turns to Group F this morning, as beaten finalists of four years ago - Croatia - take on Morocco at the Al Bayt Stadium.
Kick off there is at 10am Irish time.
The other match in that Group has a 7pm start and sees Canada play their first World Cup game since 1986, with Belgium the opposition.
Belgium manager Roberto Martinez says his players need to be calm.
Four time World Cup winners Germany open their Group E account against Japan from 1.
And at 4 o'clock, 2010 champions Spain take on Costa Rica in Doha.
