Swans boss Roberto Martinez insists he does not have a full-back crisis despite watching Stephen O'Halloran limp off against Sheffield United.Aston Villa loanee O'Halloran was stretchered off after sustaining suspected cruciate ligament damage to his knee following a tackle with Blades striker James Beattie.

Fellow full-backs Marcos Painter and Fede Bessone are also on the injury list but Martinez, who watched Alan Tate fill in admirably on Saturday, is confident his squad can cope.

"It is a specific position, especially with the way we play," he told the Swansea Evening Post. "I think with the way Sheffield United played, Alan Tate suited his role fantastically well.

"He can play in a number of positions and that is a great strength. But we will assess the injury first and we will look into it after."
