Seven Germany players are suffering mild flu symptoms ahead of the quarter-final match against France today, coach Joachim Loew said in a German radio interview without identifying the players.

“Seven players have somehow come down with slight cases of the flu,” Loew was quoted telling Germany’s ARD radio. He said that most had “throat aches” but did not reveal their names.

“As a result, it’s too early to make any final decisions about the line-up,” Loew added.

Defender Mat Hummels missed Germany’s round of 16 match against Algeria on Monday due to a fever. He said on Wednesday he had recovered and posted a picture of himself sitting on the beach.

Reserve midfielder Chris-toph Kramer was suffering from a case of the chills on Wednesday and was the only player who did not take part in the training session, said assistant coach Andreas Koepke, who added all other players were fit and ready to travel to Rio de Janeiro.

Loew has said that the travel across Brazil and different climate zones for their four matches so far as well as matches in tropical heat, a heavy downpour and then in chilly Porto Alegre – along with air conditioning – had taken their toll.
