Goalkeeper Jens Lehmann has refused to commit his future to Arsenal, but would not be drawn on reports linking him with a return to Germany.
Lehmann is the subject of intense speculation regarding his future, but the stopper would not comment on reports linking him with Hertha Berlin and Bayern Munich.
"I am in a situation at the moment where I have to make a decision at some point, but there is no fixed date for that to be made," he said.
"Every week, a new club is linked with me, while everybody knows I am also happy at Arsenal.
"I'd rather not talk about it all."
Instead, he too has been doing his homework on the Czech Republic and knows he is in for a busy night when Germany travel to Prague on Saturday.
He will come up against former Dortmund team-mate Jan Koller, while present Arsenal colleague Tomas Rosicky will also be looking to get one over on him.
"Koller is a good player and almost all of the attacks go via him," added Lehmann.
"I know nothing is going to be easy pickings in the 18-yard box.
"Rosicky is very dangerous and the only advantage we can take is that he has had a few niggling injuries recently and maybe is not fit for the full 90 minutes."
