Germany coach Joachim Low has included eight Bayern players in his provisional squad for Euro 2012, the majority of whom are training in the south of France, but they will not be put under pressure to arrive before the weekend as initially planned.
"The tendency is now going towards varying things a little to give them a bit of breathing space," the national team's general manager Oliver Bierhoff said.
"But they should all be here by Saturday or Sunday at the latest."
Bierhoff says he will leave the decision to the players individually when they feel ready to put the Champions League behind them and turn their attention to Euro 2012.
However, he does not expect any of them to have fully come to terms with finishing as runners-up in three competitions this season ahead of Friday's friendly match against Basle.
"There probably won't be any Bayern player in Basle," he said in Kicker magazine.
"The players who have already been in our training camp should be given a chance there."
Meanwhile, Germany's assistant coach Hans-Dieter Flick has revealed Miroslav Klose is winning his fitness battle ahead of next month's tournament.
The Lazio striker missed much of the last month of the season with an ankle injury, but he made an appearance on the final day of the Serie A campaign and earned a call-up to Low's provisional squad.
He has spent the last 10 days on an individual training plan, and Flick told a press conference: "He is totally on course.
"He has a few muscular problems in his back, but we are confident he will train tomorrow [Wednesday].
"If Miro doesn't have these little niggles on Saturday, then he will definitely play."
Germany face Switzerland in Basel at the weekend in one of two warm-up games before flying to their Euro 2012 base in Poland.
With Low not be fielding any of his Bayern contingent in Saturday's game, Klose and Stuttgart's Cacau should both get a chance to stake a claim for a place in the team ahead of Bayern's Mario Gomez.
"We have got to prove ourselves and show what we are capable of," said Cacau.
"This helps us to increase the adrenaline and tension ahead of the European Championships."
Low must reduce his current squad of 27 players to 23 in the next seven days, which is why the Switzerland match is such an important date for his fringe players.
Germany's clash with Israel, in Leipzig on May 31, comes two days after Low hands in his final squad selection to UEFA.
