Michael Ballack admits he does not know how long a thigh injury
will keep him sidelined for.
The Chelsea midfielder was forced off during Germany's 3-1 victory
over Switzerland on Wednesday.
The Blues ace is just the latest big name to join a long list of
crocked stars at Stamford Bridge.
Speaking after the game in Dusseldorf, and looking in pain, Ballack
said: "It is definitely a strain, but I hope it's not
serious.
"We have to wait and see in the next few days how the pain is. I
hope it does not get worse.
"The injury is annoying for me.
"I've been getting through the season quite well in terms of
injuries, so picking up a knock in a friendly like this is annoying
and unfortunate."
