The German made the revelation in an interview with the News Agency of Nigeria in Lagos.
Rohr said Musa would remain an integral part of his plans for the World Cup if his transfer back to Russia would materialise.
“Musa playing in Russia is a positive development so that we will have the sympathy of Russian fans. We have seen that when Brian Idowu was introduced in the game against Argentina.
“The fans encouraged us and he scored, this can be a good reason to get support from Russian fans because the people there like Musa.
“Also, Musa knows the people there because he is familiar with them, he knows the weather conditions too.”
On Vincent Enyeama, Rohr said the veteran goalkeeper has a chance of breaking into the team.
He said, “We are waiting for what will happen to Enyeama, if he plays for his club and gets more playing time, he can make it.
“He’s been delayed now because of his injury and now, he has about two goalkeepers ahead of him, so he has to change clubs during this FIFA transfer window.
“We also have other good goalkeepers, when I arrived, Carl Ikeme did well but now out because of illness; we are praying for him, then, Akpeyi who played against Algeria but unlucky against South Africa.”
Rohr said that in considering who gets the shirt in Russia, fitness of each playing would be the first consideration and also the competition among options in the same position.
“The first consideration is the fitness of the player if the player gets a regular playing time in his club.
“Then, I also consider the options we have on various positions we have in the team, the players will be given equal chance to prove themselves, then the technical bench will decide.
“We also have good defenders too, Ebuehi is on his way to Benfica; I told him he is good but he must be playing, so if he does not play, no chance for him.
“For Alex Iwobi, he had a little issue, but I am happy the fatherly role Wenger played by giving him a second chance. I have been in constant touch with coaches of Nigerian players,’’ he said.
