Germany's assistant coach Hans-Dieter Flick has told reporters that striker Miroslav Klose is winning his fitness battle ahead of next month's Euro 2012 tournament.

Klose, 33, was included in the squad despite missing most of the final month of the Serie A season. He returned on the final-day and has spent the last ten-days on an individual training-programme in order to ensure his recovery.

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. If Miro doesn't have these little niggles on Saturday, then he will definitely play.''

Germany face Switzerland in on Saturday in one of two warm-up games, whilst the clash with Israel, in Leipzig on May 31, falls after the deadline for the announcement.

Ahead of the friendly encounters, striker Cacau said: “We have got to prove ourselves and show what we are capable of. This helps us to increase the adrenaline and tension ahead of the European Championships.”

Joachim Low has until May 29 to reduce his 27-man squad down to the final 23 for the European Championships, meaning the encounter this weekend carries extra-weight for several fringe players in the squad.
