"I feel great about it," Billiat tells Kickoff.com.
This might come as a surprise to some, given that Rusike seems to have stepped out of Billiat's shadow in recent months and the signs are that Ajax's right and left wingers could do some serious damage to opponents this season.
In the MTN Invitational against Manchester United, Billiat and Rusike stood out with their swift combination play and deadly runs at the Red Devil defence.
"I wish him all the best out there and I think he deserves it. He worked hard and I believe it is the right time for him,” Billiat continues.
"We will miss him if he makes it, but we will pray hard for him.
"I think it says a lot about Zimbabwean football and it is something encouraging for young people back home.
"It is something that we must learn to take seriously, because it is not easy to come here firstly and then to work hard.
"It is not easy to push harder because some people think they have made it already and they don't have another dream.
"We need this as Zimbabweans. To be aware of it, otherwise we end up playing the rest of our career here.”
