Wigan Athletic vs Blackburn Rovers tips

There is one unpopular match today.
Wigan Athletic - Blackburn Rovers.
Wigan’s form of late has left them slipping down the table, which has put them down to 17th. They’re only four points above the bottom three, so they could make a quick return to League One. But the team doesn't get their points completely. They scored 21 points, but by the expected amount they have 24 (xP).

The visitors come here in 11th place, and they’ve fallen five points shy of the play-offs. They’re without a victory in their last three matches, while they’ve won just one of their last five Championship games overall. Rovers have 5 points more, but the expected number of points (xP 25).

Blackburn have won none of their last nine league visits to Wigan (D4 L5) since a 3-0 win in January 2007. The Latics are struggling for form, but they’ve lost just once at home this term. This is absolutely a home team that can beat any opponent in the Championship.

Wigan statistics: xG=22; xGa=22; BigCh=31; BigCha=30.
Blackburn statistics: xG=21; xGa=21; BigCh=26; BigCha=27.

Almost identical rates, but Wigan in the bottom of the table. In the course of the tournament Latics will score their points.
Given that they play well in their stadium, I think they will not lose. But they can win. Why not??
