The Latics boss has revealed that duo Adrian Lopez and Ryo Miyaichi will be fit for the clash, while the remainder of the squad are fit minus Ivan Ramis, Ben Watson and Albert Crusat, who are all injured.
"Adrian Lopez played 90 minutes for the Under-21s and Ryo played 45 minutes, so I do consider them fully fit and I think they are available now," ESPN quotes Martinez as saying.
"Emmerson Boyce and Antolin Alcaraz have come through our two previous games, against Reading and Liverpool, well enough. So I do expect everyone to be available for selection apart from Ben Watson, Albert Crusat and Ivan Ramis. Probably this is the strongest we have been this season."
In terms of Wigan's Premier League campaign, the North-West club currently sit one place above the relegation zone in the table.
