Gutierrez says he will race for Haas next year

Esteban Gutierrez has confirmed the worst-kept secret in the F1 paddock -- that he will complete Haas' 2016 driver lineup.

The new American team has scheduled an official announcement to be made in Mexico City on Friday, to be streamed live on the websites of Gutierrez's sponsors Claro and Telmex.

Within the paddock, the news has been unofficially known for some weeks now, and even Mexican Gutierrez, currently the Ferrari reserve driver, is no longer hiding it.

"Next year I will race with Haas and I am very happy about it," he declared in Spanish at a sponsor event ahead of the Mexican Grand Prix

"It is a new adventure for me and I will make the most of what I have learned at Ferrari," the 24-year-old added.
