While the DFB Pokal on May 12 will leave Borussia Dortmund's players free to join up with their respective national teams, it is Bayern Munich's German internationals Loew may be concerned about, as he will only have them at his disposal after the Bavarian club's May 19 Champions League final date with Chelsea.

These fixtures could leave the likes of Manuel Neuer, Philip Lahm, Mario Gotze and Mats Hummels physically and mentally jaded according to Loew and a late call-up for Bayern's players grants the 52-year-old coach less time to have his men ready for Germany's friendly against Israel on May 31 and the competition in Poland and Ukraine itself.

"Of course I'm very divided, because some of my players could join me being very disappointed," Loew told Bild.

"The disappointment goes away, I know, but it takes several days to digest it all, while fear of injuries is a natural concern. There will be hard challenges, so you can't rule out anything. But my hope is that no one arrives badly hurt.

"I will also only have one-and-a-half weeks to work with my entire squad. That all said, you have to live with these uncertainties as a coach. I have no choice, I will not complain."

Germany kick off their Euro 2012 campaign against Portugal on June 9.
