Didier Deschamps has revealed France are taking precautions to stop a virus spreading through the squad before the World Cup final against Argentina.

Dayot Upamecano and Adrien Rabiot were unavailable for Wednesday's 2-0 semifinal win over Morocco at Al Bayt Stadium after suffering with sickness in recent days.

Although Deschamps is hopeful both players will be able to return for Sunday's showpiece -- where Les Bleus could become the first team to successfully defend the trophy since Brazil in 1962 -- he revealed the pair had been initially been isolated from others.

Upamecano returned to training on Tuesday and was named on the bench against Morocco while Rabiot was left back at the team hotel with sources telling ESPN he was told to stay in his room.

Kingsley Coman was also "feverish" earlier in the day according to Deschamps. Although the specific virus affecting the France camp is as yet unclear, many visitors to Qatar have struggled with Middle East respiratory syndrome, which can cause a flu-like illness ranging in severity.

"In Doha, temperatures have fallen a little bit, you have air conditioning which is on all the time," said Deschamps.
