Malky Mackay
The former Cardiff boss is now the clear front-runner to succeed Tony Pulis at the south London club, but Palace have remained tight-lipped on the situation.
Selhurst Park bosses are believed to be close to finalising a three-year contract for Mackay, with bookmakers suspending bets on his appointment.
Former Tottenham bosses Sherwood and Martin Jol had been under serious consideration by the Palace board, but Mackay's close relationship with sporting director Iain Moody should tip the balance in his favour.
