Arun Sarin, the former head of Vodafone (NYSE: VOD), is showing strong interest in succeeding Jerry Yang as Yahoo’s CEO, according to The Financial Times, which quotes people who are close to Sarin. Yesterday, it was reported that Sarin’s name was the latest being floated for the job. The FT’s sources stressed that Sarin has not made a decision on whether to join Yahoo (NSDQ: YHOO), and is considering other alternatives, including chairing Yahoo’s board, or joining a private equity firm. A Yahoo official in the story said it is premature to speculate on who Yang’s successor might be, while an unofficial source close to Yahoo said the company has not made any offers yet.
