Red Bull blocks Vettel from Ferrari test after saying yes

The four-time world champion is leaving Red Bull for the Scuderia after spending his entire racing career as a protege of the energy drink company.

He was expecting to join Ferrari for the Yas Marina test next week, but Red Bull has changed its mind because it fears he would take secrets with him.

"Yes," the German replied when asked if Red Bull had blocked the test.

"It is a shame, especially because initially I was allowed and then I wasn't. It is what it is.

"I don't know [why it happened]. All of a sudden something changed, I think as far as I understand, I don't know.

"The technical people were panicking a little bit, afraid I might take some secrets…"
