The Latics will haul their way out of the bottom three at Villa's expense if they manage to end their run of six matches without a win.
Yet even victory against a team that has conceded 12 times in its last two games won't have Martinez sleeping easily as the transfer window is looming.
And whilst Martinez has already started the process of bringing in new players - Angelo Henriquez on loan from Manchester United and Honduran midfielder Roger Espinoza - others are being linked with moves elsewhere, namely goalkeeper Ali Al Habsi and striker Franco di Santo.
"I don't agree with the window being open whilst you are playing official games," said Martinez.
"Sometimes we forget about the human part of the footballer.
"Everybody wants to hear what the next step in their career is. But that can become very disrespectful to the team and the fans when you are playing games.
"Victor Moses played against Chelsea in the opening game and their fans were singing 'we'll see you next week'. That is how incredible this situation is.
"Players should be allowed to think about their careers and their next move at the right time.
"In our case, these next five or six matches could be the most important five or six games in the club's history."
