The Dons will be aiming to become the first Championship side this season to lower Leigh Centurion’s colours in Sunday’s eagerly-awaited clash at the Keepmoat Stadium.
But player coach Paul Cooke is under no illusions just how big a task it will be for his fourth-placed side to do so in the competition’s match of the day.
“They are the best side in the division by a mile,” said Cooke.
“If they are at their best and whoever they are playing in this division plays at their best on the day, then there is only going to be one winner and that is Leigh.
“They have won all 18 league games and they are trying to go through the season unbeaten.
“But the closer they get to that target the more pressure will build on their group.
“They are up there to be shot at.
“Everyone they play are wanting to become the first team to beat them and we’ll certainly be giving it a good go this weekend.
“We’ll be going into the game knowing that if we play to the best of our ability we’ll be there or thereabouts.
“We also accept that Leigh have also got to be a little bit below par on the day to get a result against them but we are certainly looking forward to the challenge.
“As I say, they are strong throughout the team.
“But there are always chinks in everyone’s armour and we’ve identified some areas where we feel we might be able to capitalise.
“The obvious thing for anyone who plays Leigh is that you’ve got to defend well.”
The Dons go into Sunday’s game just two points behind second placed Featherstone Rovers.
Rovers have faltered in some of their recent outings, and Doncaster have a glut of games at the Keepmoat, where they have lost just once this season, still to come.
“We’ve put ourselves in with a chance of finishing second but we are not getting carried away,” said Cooke.
“We’ve got six of our remaining eight games at home but we spoke about it as a staff earlier this week and those games have still got to be won.
“We are finding out from other team’s results that games are not always going the way people expect them to.
“So we’ve really got to work hard to get the results in games that people are expecting us to do well in.
“It’s not about how other teams are doing, it is about us as a team stringing some performances together.”
