“It is true that next year Jerry won’t be my chief mechanic,” Rossi told the press conference. The decision had not been taken lightly, he said. “It was a very difficult decision for me because I have a great history with Jeremy. He is not just my chief mechanic. He is like part of my family. My father in racing.”

Rossi felt he had been forced to make a decision to try to make a change, to regain his competitiveness. “I’ve decided for next year I need to change something to try to find new motivation and to have a boost to improve my level, my speed. So this will be my last race together with Jeremy.”

Rossi had made the decision five days ago, he told reporters, but had waited until Valencia to tell Burgess, once he could tell him himself. “We spoke today, face to face. Next year will be crucial and I need new motivation. In the last few races I’ve felt I wanted to work in a different way. It was a difficult choice to make. Yamaha had asked me some time ago, but I decided recently.”

No decision had yet been made about a replacement, and it was unclear whether Burgess would be present at the test.
