Mainz: Germany's 6-1 friendly win over Armenia on Friday was overshadowed by the ankle injury which threatens to rule left winger Marco Reus out of the World Cup.
The 25-year-old was rushed to hospital having being helped off in obvious distress after twisting his left ankle just before the half-time break in a challenge.
Andre Schuerrle gave the hosts a second-half lead and although Armenia's Henrikh Mkhitaryan converted a penalty, the floodgates opened as Germany scored five goals in the final 17 minutes.
Goals by Lukas Podolski, Benedikt Hoewedes and Mario Goetze, who scored twice, did the damage to floor minnows Armenia.
Replacement Miroslav Klose, who turns 36 on Monday, made history when he headed home their fourth to become Germany's all-time top scorer.
Klose netted his 69th goal for Germany on his 132nd appearance to finally break Gerd Mueller's previous mark of 68 goals in 62 matches for West Germany.
Both captain Philipp Lahm and his deputy Bastian Schweinsteiger played in Mainz after injury, but Reus' injury is a big concern for head coach Joachim Loew.
Armenia squandered a golden early chance when Borussia Dortmund's Mkhitaryan played a great pass, but Gevorg Ghazaryan could not get his shot away and the opportunity went begging.
At the other end, his Dortmund team-mate Reus combined with Thomas Mueller, who was playing up front as Germany's 'false nine', but his shot was cleared by defender Hrayr Mkoyan as it rolled towards the empty net with 13 minutes gone.
Reus' injury put a dampener on the first-half, but Germany got the break-through they needed when his replacement Podolski supplied a superb cross on 52 minutes which Chelsea's Schuerrle converted.
Armenia pulled a goal back when Kevin Grosskreutz conceded a penalty after a foul on Mkhitaryan less than a minute after coming on.
Germany went ahead three minutes later as Podolski fired home after a good pass from replacement Mesut Ozil on 72 minutes.
Schalke's left-back Hoewedes grabbed the third when he followed up and netted his own saved shot on 73 minutes, then Klose made history with a header four minutes later as the floodgates burst.
Podolski looks to have played himself into Loew's starting line-up for Germany's World Cup opener on June 16 against Portugal.
He provided his second assist when he thread a superb pass through for Goetze to slid home Germany's fifth as Loew got the win he wanted before heading to Brazil.
