Didier Deschamps is concerned his France players will not be able to cope with the sweltering heat of Brasilia in tonight’s second round match against Nigeria.
In a World Cup dominated by South American teams, France have been one of the few European success stories so far.
Deschamps’ men topped Group E with two wins and a draw, scoring eight goals in the process.
The French were helped by the fact that all their group matches took place either at 1600 or 1700 local time.
But that will not be the case when they take on Nigeria in the Brazilian capital, where the temperature is expected to hit 30 degrees Celsius.
Deschamps has changed his squad’s eating patterns – they had a lunch of pasta and fish at 9:30am – to try to help them be ready for the early kick-off, but he is still a concerned man ahead of the match.
“Yes, the heat worries me,” said the France coach.
“Nigerians are naturally more adapted to heat.
“The match is at a different time so over the last three days we have been trying to adapt to this schedule by changing our food.
“You need to manage these problems.”
