Steve Bruce has coughed up £100,000 to Birmingham City to gain his release and take charge of Wigan Athletic.
Birmingham are set to receive £3million in compensation while Bruce's four-year deal is worth £8m.
He was due to sign his contract in front of the TV cameras on Wednesday but his seat - and that of chairman Dave Whelan - remained empty because of the last-minute hitch.
He is now likely to be unveiled on Monday and will take his first training session later that day.
