West Ham United co-owner David Sullivan admits their relegation battle has given him sleepless nights.
Sullivan, who acquired West Ham with David Gold last January, claims no one could possibly imagine how the pair are suffering.
Sullivan told the Sunday Mirror: "Don't talk to me about Christmas. I'm spending every waking hour trying to address the problems at West Ham.
"I can barely sleep at night with worry. In fact, most nights I wake up terribly depressed and worried sick.
"I feel like I have gone six rounds in a boxing ring and taken a battering.
"My only hope is there are six more to go and I can stay on my feet long enough to survive."
