Rose is currently on loan at Sunderland but Villas-Boas confirmed he had spoken to the 22-year-old, who was sent off after the final whistle in the Euro 2013 play-off in Serbia.
He said: "It's extremely difficult for Danny. He was disappointed by that happening, by the situation which he had to live with, the atmosphere he was confronted with.
"I told Daniel I support him completely in this situation. He felt abused and this is obviously a serious matter which at the moment is in the hands of both FAs."
