Wigan's plan to unveil Roberto Martinez as their new manager descended into farce.

While Martinez sat patiently in the DW Stadium expecting to be presented to the waiting media, a sudden and unexpected hitch developed behind the scenes.

And he effectively remains Swansea's manager after the Coca-Cola Championship club demanded compensation for the backroom staff he wants to take to Wigan.

The dispute centres around his assistant Graeme Jones, chief scout Kevin Reeves, goalkeeping coach Inaki Bergara, physio Richie Evans and fitness coach Oscar Brau.

A Wigan spokesman confirmed: "There is going to be no resolution today as we are still talking to Swansea."

Earlier chief executive Brenda Spencer appeared alone at a press conference to reveal the formalities over the Spaniard's deal could not be completed until a agreement was reached over his support team.

Spencer said they had been unable to contact Swansea chairman Huw Jenkins since last night - when she held further talks with Martinez - but were still hopeful of concluding the deal.

"We have an agreement with Roberto verbally but he cannot sign at the moment to be our manager until Swansea sign the agreement between the two clubs," said Spencer.

"It's absolutely frustrating because at no time over the last week have Swansea ever mentioned anything about backroom staff."

Wigan chairman Dave Whelan insisted this week it was a "done deal "and the club are ready to continue negotiations over the additional staff.
Spencer said: "We have an agreement for Roberto, we just have to see what compensation they want (for the rest). Unfortunately we cannot get hold of their chairman at the moment.

"We just have to get on to Swansea about compensation for backroom staff.

"We hope to get something sorted today or tomorrow but certainly early next week.

"At about 11am this morning we did think this was something we could sort out in time but until we get hold of the Swansea chairman there is not much we can do.

"I'd just say to the fans to hold on tight and keep their fingers crossed and their toes crossed and hopefully Roberto will be our manager today or tomorrow."

Martinez guided Swansea to the League One title in 2007-08 before steering them to an eighth-placed finish in the Championship in the season just ended.

He joined Wigan as a player in 1995 and stayed six years, plying his trade in England's lower leagues before eventually turning his hand to coaching and management.
