NEW YORK/PHILADELPHIA, Sept 25 (Reuters) - Struggling savings and loan Washington Mutual Inc WM.N is still talking to buyers about selling itself, but first needs to hammer out whether it or the buyer would get government support.

Banks still circling all of WaMu include Citigroup Inc (C.N), JPMorgan Chase & Co (JPM.N), HSBC Holdings Plc (HSBA.L) and Wells Fargo & Co (WFC.N), while Toronto-Dominion Bank (TD.TO) is looking at pieces, according to sources familiar with the situation.

There is also private-equity interest from Blackstone Group LP (BX.N) and Carlyle Group [CYL.UL], which could team up with Texas billionaire and bank investor Gerald J. Ford, a source said.

Spain's Banco Santander SA (SAN.MC) has withdrawn as a suitor, one of the sources said.

Sources previously had told Reuters that regulators are eager for the giant savings and loan to forge a deal, but no deadline or requirement has been placed on the bank to accept a takeover offer or split itself among several suitors.

The main auction has been slowed as the government talks to potential suitors about possible financial support for a deal.

However, the pressure is on to strike a deal for the troubled Seattle-based thrift amid continued uncertainty in the financial sector.
