With confidence in the camp already high, Martinez could be given another boost with the return of two of his most dangerous attackers.
"With Hugo we are getting closer. It is too early to tell if he is going to be ready for Saturday but he is progressing really well," said Martinez.
"It is similar for Shaun Maloney, who is 50-50 for the weekend. I hope he is going to be able to join the group on Friday and we will see how he develops from there."
Wigan are currently five points clear of the Premier League relegation zone.
