Germany coach Joachim Low says he has fears that form and fitness will come back to haunt his side at the World Cup.
The Euro 2012 semifinalists dropped just two points in an emphatic qualifying campaign and are among the pre-tournament favorites to win the prestigious trophy in Brazil this summer.
However, the coach has a host of injury concerns to contend with that could dent the team's World Cup hopes: Bastian Schweinsteiger, Ilkay Gundogan, Sami Khedira, Mats Hummels and Mario Gomez have all struggled for fitness this season, while Miroslav Klose is a doubt for Wednesday's friendly against Chile because of a pelvic problem.
"On paper we have a top team with top quality and top individuals, but the reality looks a little different," Low told reporters. "The truth is not so nice because many of our players have been injured for a long time and don't have much rhythm, be it due to a dip in form or niggling injuries, which is why we need to use these next two and a half months to improve and do everything to reach top form.
"The clock is ticking and I'm making an appeal to everybody to prepare as best as they can and to invest all they can, not only to be physically but also psychologically ready for this. We need a very good core and some of my players are still showing deficiencies."
On a more positive note, up to four players could make their international debuts Wednesday and Low confirmed that there is still time for players to make the plane for Brazil.
"Anybody in my squad has the chance of coming to Brazil and I know I'm going to have to hurt one or two people with my final squad decision," he added.
