"I am very disappointed and shocked by the decision taken by Scuderia Toro Rosso of not allowing me to drive for the Team until the end of the current season.
"I consider that, in doing so, Scuderia Toro Rosso has breached its contractual duties towards me; also I believe that nothing in my behavior would legitimate a decision of the Team to terminate the contract. I think that the Team’s decision is in clear violation of Scuderia Toro Rosso’s obligations under the agreement. I have instructed my lawyers to review the situation including the possibility of issuing legal proceedings.
"I am even more frustrated by the Team’s decision considering that the latter has been taken immediately before the Hungarian Grand Prix, where a new highly competitive racing package will be introduced by the Team in order to try and overcome its current difficulties. I am convinced that if I was given the chance to race with such new package I would have had the opportunity to achieve satisfactory results.
"Finally, I would like to thank all my fans for their support. My motivation is intact and I will continue to be strongly committed to my Formula One project, for which I have renounced to my career in United States."
