Yas Marina chief to work on Russian GP
"The combined, impressive experience that the international consultants have, their understanding of the Formula 1 world, and the desire to do the F1 Russian Grand Prix at the highest level guarantee a good result of our teamwork," said Zabara.
"The knowledge and experience which we will get in the course of this co-operation will ensure not only the hosting of a world-class grand prix, but also effective use of the autodrome in Sochi all year round."
Cregan will remain involved with Yas Marina as an advisor.
"Moving on from Abu Dhabi was a tough decision for me but I have always enjoyed a new challenge and remain an advisor to the chairman and management there," said Cregan, who has been part of the Yas Marina project for the last five years.
"I am convinced that the F1 Russian Grand Prix will become one of the iconic events in the Formula 1 calendar and we will be able to build a very successful business by utilizing the amazing assets and the passion of the team here in Sochi."
