Crystal Palace boss Sam Allardyce admits his January market work has given him sleepless nights.

Allardyce certainly doesn't need any outside distractions to the job at hand this month, and says his wife will move south once the transfer window closes.

"I don't sleep! I only do four or five hours a day, so I can stay awake and watch games and do lots of stuff when it's quiet," said the 62-year-old.

"When people are asleep you can concentrate and focus on the iPad or the television watching players.

"The wife isn't with me at the moment so she's glad about that! She said she'll stay up there while I'm down here, as she wouldn't see me anyway!

"She'll be down in February once I've found a pad to rent."
