Martinez, who has engineered the Latics' safety in the closing stages of the last two seasons, believes this year will see a much tighter finish with several teams battling each other to pass the magic 40-point barrier and secure safety.
Wigan are currently second bottom.
Roberto Martinez: "This year the bottom 10 positions are really open.
"I know that now people are looking at the table but I don't think it shows the reality of the teams that are involved. There will be a lot of twists and turns from now until the end of the season.
"It is going to be a ferocious fight until the end of the season for all of the bottom ten clubs.
"A lot of teams are going to get involved because if you don't get the 40 points that you need you are going to be fighting to avoid relegation.
"There are ways of winning football games and everyone will have a say from now until the end of the season."
