The Chelsea striker has joined BVB on-loan to the end of the season.
Stoger said: "It's up to us how quickly we put him into the system. Michy will certainly be in the squad.
"He's hungry and motivated and he wants to go to the World Cup, so that's good news for us.
"He's hard-working and dangerous in the penalty area. He had a good record at Chelsea and I think he fits in well with us."
