The French centre-back has given the green light on personal terms to join the Eagles on loan.
Liverpool wanted to sell Sakho permanently but Palace haven’t met their £20m valuation.
It means they will have to settle on a loan deal for a player that hasn’t featured for the club since April.
With less than two hours left of the transfer window, Liverpool still hadn’t announced a deal had been done.
Crystal Palace hadn’t made an official announcement either – but both clubs have been in Premier League action.
Palace hadn’t wanted to make any announcements in the run-up to the clash as Sam Allardyce didn’t want to distract his squad.
But Starsport understands soon after the full-time whistle is blown at Liverpool, the move will be officially confirmed.
Sakho was spotted at Euston train station this morning ahead of his Anfield exit.
