I think the process is still at an early stage, and I don't think it's a two horse race just yet.
Our interest in Martinez became public only when Whelan opened his yak and talked to the media (inevitably), and Villas Boas was always going to be a contender since he was rumoured to be FSG's number one target when they first came in.
Frankly, if you're an employed manager and Liverpool Football Club approaches you to see whether you're interested in the manager's job, its in your best interests, and the interests of LFC, to keep quiet about it.
No one knew that Liverpool had approached De Boer until he came out and said that he had rejected an approach. I expect that other managers who were approached, and are interested in the job, would not disclose any information to the media.
