Jonas Eidevall’s side are three points behind WSL leaders Chelsea, who are level on points with Manchester City.
The Gunners beat Emma Hayes’ side 4-1 in December’s reverse fixture.
“It’s huge. If Arsenal win, they’ve closed that gap on Chelsea,” former Arsenal striker White told BBC’s Women’s Football Weekly podcast.
“To gain those three points and be in an incredible position for Arsenal would be a big one. It could really flip things up.
“We want every game to be exciting, not sure what will happen and go down to the wire. We don’t want one team to run off and it be so obvious who’s going to win.
“You want that competitiveness. I feel every game is a real challenge for each team now, which is really exciting.” BBC Sport
