Blues boss Jose Mourinho has told Van Ginkel he wants to keep him involved this season, but is yet to select the Dutchman.
Agent Rob Jansen concedes Van Ginkel could still be sent away.
"We hope not, because that would be against all agreements. But you never know when it comes to these clubs," said Jansen.
"We'll see if they keep their word. There may even be a change on the last day."
