Wigan have a clean bill of health and know that any kind of result at Ewood Park is likely to see them safe for another season.
Martinez won't play for a draw though, and will field the same side that trounced Newcastle 4-0 last time out.
Their apparent 5-4-1 formation can quickly change into a counter attacking 3-4-3, with Beausejour and Boyce moving forward to the wings and Moses and Maloney supporting Di Santo.
This is a huge game for both sides and Steve Kean knows that defeat would probably see them relegated but a win could put them on equal points with Bolton and QPR if those two sides were to lose on Sunday. Playing a day later, they know that if either of those sides win they will have to do the same.
A victory for Wigan would see them safe and ensure another excellent escape by Roberto Martinez's side, with the manager attracting plaudits for his brave tactical decisions in the latter half of the season.
The last two games between these two sides have seen 13 goals scored, including a 3-3 draw earlier in the season, and you can expect goals again and perhaps an individual error proving costly in this one.
