Two days after being offered Uber’s top job, Dara Khosrowshahi, who is currently chief executive of Expedia, says that he has still not signed his contract but is likely to take the position.

Mr Khosrowshahi made his first public remarks about what he sees ahead for Uber in interviews as part of an Expedia media day – comments that were unusual because Uber has still not formally announced his appointment, and Expedia has not announced he is leaving.

“It’s definitely the opportunity of a lifetime,” he told Bloomberg. “Are there difficulties? Are there complexities? Are there challenges? Absolutely, but that’s also what makes it fun. I am not in this to coast. I’m in it to get my hands dirty and build a team and do something that people will look back on with tons of satisfaction.
