The January transfer window is a stressful period for all managers yet Tony Mowbray is literally losing sleep over his bid to bring Kim Do-Heon to the Black Country.
The West Bromwich Albion manager has made an undisclosed offer for Do-Heon having been impressed when the South Korean international arrived on trial from his club Seongnam Ilhwa Chunma last month.
But it's not that negotiations for the 25-year-old are not progressing as Mowbray would like, it's the time at which they are being done which is causing him most concern.
"It is ongoing and if we can do it we will do it," Mowbray said. "We are trying to deal with someone who is living in Korea and phoning me at strange times.
"There is an eight-hour time difference and sometimes they don't do their calculations very well when they make their calls.
"I also have some lovely pictures on my computer of his wedding. The agent is trying to get across this is a big star in Korea, there were thousands at his wedding and he is sending me the pictures to make sure I am aware of it."
Despite phone calls in the dead of night Mowbray is not overly anxious about the weeks ahead and he maintains he is neither desperate to bring anyone in nor worried about losing some of his top players.
Paul Robinson and Zoltan Gera are reported to have attracted a joint bid from Bolton Wanderers, managed by former Albion boss Gary Megson, while the Hungary captain has also interested Middlesbrough.
Wigan Athletic manager Steve Bruce is also attempting to sign Robinson, a player who interested him when he was in charge at Birmingham City.
But Mowbray is adamant he is under no pressure to buy or sell. "We don't need to sell and no one is going to come in and nick anyone," he maintained.
"Why would we sell? We have given ourselves a good platform for the season and we don't want to derail that. I want to be over-flowing with top players and that means players who are talented."
Mowbray also revealed Albion are close to finalising a permanent transfer for Dutch striker Sherjill MacDonald, aged 23, who has been on loan from Anderlecht. The Baggies hope to sign Viktoria Plzen's Czech keeper Michal Danek as well.
But there are likely to be some players leaving the club too. Mowbray confirmed his former Manchester United midfielder Ronnie Wallwork may not be around much longer and Albion will do all they can to off-load John Hartson.
"One or two may go, those who can't see a chance to get into the team," he admitted.
"Ronnie Wallwork has just come back from a loan spell at Huddersfield but they hope to do a permanent deal so that is ongoing."
Meanwhile Bartosz Slusarski's loan spell at Blackpool has been extended by a further month. The Polish international joined Albion's Championship rivals in November and has so far scored once in four starts and two substitute appearances for Simon Grayson's men.
