It was only on Friday that Microsoft announced that current CEO Steve Ballmer would be exiting the company in the next twelve months, but that hasn’t stopped the media from speculating on who will replace him. The Sunday Times of London is now reporting that Nokia CEO Stephen Elop, who used to work under Ballmer as a senior executive—something that always bothered Nokia advocates who saw him as threat to the Finnish phone maker—as one of the favorites for the position.

One could argue that Elop does have the skills to turn around companies who are seemingly set on a wrong course, though he doesn’t come without controversy either. Many former Nokia supporters have consistently called for his ouster since his famous burning platform memo, which called for drastic change within the company for it to survive.
