Keane concern for Ireland
The 33-year-old did not train at the Rhein Energie Stadion on Thursday evening because of an ankle injury picked up in Malahide on Tuesday, and interim manager Noel King will make a late decision on him.
Speaking at his pre-match press conference in Cologne, King said: "He has a bit of an ankle problem. He's not training tonight - we will just leave him out as a precaution - and we will make a decision in the morning about him."
Keane aggravated a long-standing condition when he took a kick on the ankle in training.
King said: "He got a little kick on it. It's something that comes and goes with him over the last number of months and he got a little kick on it, so it's a worry.
"When wakes up in the morning, we will get at it straight away."
King said: "He is healing, and that's the process, so he's being tended to and we are hoping he will be ready for tomorrow; if he doesn't make tomorrow, we are hoping he will be ready for the next game.
"There's no question of going home or anything like that. He's still in squad."
King confirmed that Keane, Ireland's record scorer with 60 goals, would start if he was fit, although all the indications are that he is struggling.
Galaxy boss Bruce Arena this week had a request to release his player after the Germany game politely rejected, but asked if Keane would have a painkilling injection in a bid to play, the stand-in boss insisted that would not be down to him.
He said: "That would be a medical situation, that would be for [medical director] Alan Byrne, himself and his club. We wouldn't do anything without talking to the Galaxy. They know about the situation, so that would be pretty much out of my hands."
He said: "Robbie been one of our leading lights over the years, he's the leading scorer, one of the leading scores in Europe. If he doesn't make it, we wouldn't be happy about that, that's for sure.
"But we would get on with it. There's nothing we can do about it. If he goes, he goes and the person who comes in will be delighted with the opportunity and delighted with the cap."
King was giving little away about his team selection, although Damien Delaney's presence as the press conference - Keane would normally have accompanied the manager as captain - suggested he will occupy one of the central defensive berths left vacant by the suspended Richard Dunne and John O'Shea.
He said: "I have fair idea. I probably have about 10 right and I am just working on in my own mind. Then obviously with Robbie's situation, we will have to see how that pans out as well.
"I don't have to name it now, so now why should I? It's extra day for us, a bit more knowledge and we will see.
"They [the players] will know first, they will definitely know first. They will know in the morning."
Ireland cannot qualify for next summer's finals in Brazil, while Germany would book their ticket should they claim three points to go with those with which they returned from Dublin last October after a 6-1 rout.
German midfielder Sami Khedira has urged his team-mates to hit Ireland with an early blitz to make the result a formality, but King insisted his team would be prepared for that.
He said: "I don't think we need him to tell us that. We are aware of the Germans, we are aware of the onslaught we may face at start and at any time during the game, so we need to be fully concentrated for the 93, 94 minutes that we play, so that wouldn't change our view."
