Wigan have apologised to their fans for delaying the appointment of Roberto Martinez as their new boss.
The club are currently embroiled in a financial tug-of-war with Swansea over the amount of compensation for the Spaniard's backroom staff.
It is believed he has signed a three-year deal to replace Steve Bruce at The JJB Stadium but the 35-year-old was not unveiled to the media at the ground on Thursday.
A club statement said, "Wigan hoped to unveil Roberto Martinez as new manager yesterday. But due to Swansea City wanting further compensation for Roberto's backroom team it was felt that delaying the announcement of Martinez was the only option.
"Wigan would like to apologise to the media at yesterday's event and to the supporters for the delay.
"The club would like to stress that talks with Roberto have been extremely positive and personal terms have been agreed.
"We are confident to resolve the issue by early next week. We have already agreed a compensation package to Swansea City for Roberto and talks are ongoing between the clubs about the backroom staff.
"Once these issues have been resolved we will be able to unveil Roberto as new manager and get on with the job of preparing for next season. Thank you all for your patience."
