Following recent reports that Microsoft was interested in a bid, troubled Yahoo could have another potential buyer in the form of Google.

The Wall Street Journal reports today that Google has been in discussions with at least two private equity firms about assembling a co-financed bid for Yahoo’s core business. However, the newspaper’s sources say that nothing is certain yet and a formal proposition hasn’t been assembled thus far.

Yahoo has been reportedly considering a sale since its board fired CEO Carol Bartz last month. Microsoft is one big name that has been mentioned, and a mooted merger with AOL was also reported. Meanwhile, another report said that Yahoo was considering selling off its interests in Asia separately. A replacement CEO for the company is yet to be appointed.

With Yahoo seemingly unable to find a solid place in today’s online landscape, a sell-off makes plenty of sense, although if Google were to be involved it would undoubtedly face close scrutiny from antitrust authorities – the FTC is already investigating the search giant in the US.
