Hiddink will stay as Chelsea manager until the end of the season after the club sacked Luiz Felipe Scolari on Monday.
“I’ll be working alongside Guus for the immediate period,” Wilkins said.
“He isn’t bringing anyone in for the time being. So it will be Guus and myself and then we’ll see where we go. I’ll assist Guus as much as I possibly can.
“I’m employed by Chelsea and not by the new manager. But if he wants me to disappear I’ll have to disappear.”
