Wigan coach Michael Maguire says that stopping Castleford half-back Rangi Chase will be a priority in Wednesday's Super League clash against the Tigers.
"He's definitely the key for them," Maguire told BBC Radio Manchester. "They've got a lot of other players who can perform but he is their main key.
"He gets across the park and he's hard to get a hold of, so it's something that we're working on.
"He's their go-to-man and he's got a lot of quality about him."
Chase has been one of the outstanding performers in this season's Super League, top-scoring for Castleford with 10 tries, as well as impressing at Headingley in the origin game for the Exiles.
"We saw in the Exiles game with him and Tommy Leuluai in the halves and he's one that we're definitely watching."
The two sides last met less than a month ago when a remarkable comeback from Castleford saw them overcome an 18-point half-time deficit to secure a 22-22 draw.
And it was Chase who played a major part, coming off the bench as a 28th minute substitute to orchestrate the fightback.
"Unfortunately there was a few uncharacteristic things that happened throughout that game," explained Maguire.
"But we've moved on from that now and we're in this position - we've got a good opportunity on Wednesday to be able to get two points.
"Any team in this competition can beat you if you're not on your game and we've experienced that in the many draws we've had this year.
"So it's about turning up - we're looking forward to getting out in front of our crowd and performing the way we have done the last three games."
Victory at the DW Stadium would send the Warriors back to the top of the table.
