West Ham United boss Sam Allardyce fears the sack if he doesn't get the winter market right.

He reckons the club will have been offered THOUSANDS of players during the window he regards as a nightmare.

Allardyce, who takes his team to Sunderland today, revealed: "Mistakes cost you your job, don't they?

"If I make mistakes in the transfer window and bring in players that fail, it costs me my job. It gets me the sack."
