Boss Mark Robins admits Barnsley will be the underdogs when they take on Leeds at Oakwell but insists his side will be ready for the challenge.
The Tykes will be hoping to maintain their 100% Championship home record this season against a Leeds side that have now won two games on the bounce.
Robins told Barnsley Player: "Leeds have made a seamless transition into this league. They are a big club with a good manager and some very good players. We know it will be a very tough ask but we are at home.
"Leeds will come here with a long tradition of success when compared to ourselves and people will draw conclusions from that. We want to go out and upset a few people.
"We know we will have to be on our game and be better than we have been in our three away matches this season. It's one we are looking forward to. We have two great home games this week against two big teams who we are looking forward to pitting our wits against.
"There will be a big crowd here and a lot more Barnsley supporters than Leeds. You always want to play in front of a full house. it is something we are relishing and we will be ready for it."
