QPR boss Harry Redknapp admits the January transfer window is one of the most stressful periods of the year.
Redknapp wrote in The Sun: "The January transfer window means a load of earache from hours spent on the phone.
"Then there's the stress while desperately trying to get in some players in the hope of transforming your season and possibly saving your job.
"Over the years I've had some pretty crazy times in January. The phone is ringing all the time. When I'm out having dinner with my wife Sandra it rings and the thing is you have to take the call.
"You can't switch the phone off in case you miss out on a deal or because you are closing in on one.
"You are taking a gamble when you sign players in this way and it's usually the struggling clubs that are forced to be most active in January.
"But you can pick up the odd gem."
