Speaking to the Official Club Website, former Northern Ireland international Magilton said: "Wigan still have some really tough fixtures to play.
"They have to go to Preston and QPR and Reading won't be easy by any means either so there is still plenty more to play for.
"I really believe that if we can get a good result at Leeds, we could go and win all three games and that could be enough to se us go up.
"It won't be easy at Elland Road though. No team is going to lie down and give us three points. They've got good players there with a lot of experience and on their day they can be as good as anyone in this division.
"They will roll their sleeves up and give us a game. There's no doubt it's going to be a tough match, especially with their supporters. We have to be ready for them and have the determination and hunger to get three points because it's got to the stage of season where that is what it's all about."
