Wigan Athletic chairman Dave Whelan is demanding crunch talks with manager Roberto Martinez to discuss their poor defeat to Swansea City.

Whelan was clearly unimpressed.

"That was our worst performance in four or five years," he told BBC Radio Five Live. "I will have a meeting with him on Monday morning and ask him some questions about the performance and his selection.

"We had three quality players on the bench and I want to know why."

Whelan denied Martinez's job was at risk, although clearly Wigan's top flight status is given they still have a number of top clubs to play.

"Roberto Martinez's future is secure," he said. "He has done a great job for the club.

"But we will have a meeting on Monday when he will put his cards on the table and I will do the same."
