Shaun Wane says Wigan will put thoughts of Wembley aside when they host Hull KR in Super League on Friday night.
The Warriors face Hull FC in the Challenge Cup final later this month but their focus will be on their league challenge for the next three weeks.
Wane's side surrendered top spot to the Huddersfield Giants when they lost to rivals St Helens in their last Super League fixture.
With back-to-back home games against Hull KR and the Giants, and a trip to the Catalan Dragons before their Wembley date, Wane knows those three matches could be decisive in the fight for first place.
The Wigan head coach said: "We have put ourselves in a good position to try and retain the League Leaders' Shield but we are not at the top of the competition at the moment, that belongs to Huddersfield and they deserve that.
"We have Huddersfield in a couple of weeks but the first and most important is Hull KR. All I am thinking about is Friday night and I want us to be at our best."
Wane will rest forward Liam Farrell for the visit of Rovers to the DW Stadium, with 18-year-old centre Joe Burgess added to the squad for the first time.
"I will look to give the players a chance and will use the next three games to give everyone a chance to put their hand up and give themselves an opportunity to play in that game," said Wane.
"There are some places up for grabs and the best will play."
