Chesterfield travel to the Kassam Stadium to take on Oxford United in their eighth fixture of the 2013/14 Skybet League Two season.
The Us are currently second in the League 2 table having taken 15 points from their opening seven fixtures, drawing 2-2 with Cheltenham Town in their last outing at Whaddon Road.
The Oxfordshire side finished the 2012/13 campaign in ninth place, one below the Spireites and will be looking towards automatic promotion this year.
Chesterfield approach this fixture on the back of a 2-0 win over AFC Wimbledon taking the Spireites to 19 points from their opening seven games.
Four points clear at the top of the table and yet to lose in the league, Chesterfield will be looking to continue their strong start to the season.
Oxford last hosted the Spireites in March earlier this year where an early Marc Richards goal was enough to separate the sides and award Chesterfield the three points.
Winger Sean Rigg returns to the squad after recovering from a hamstring picked up at Torquay last month.
Young striker Tyrone Marsh will miss out after hurting his ankle during the development squad game in mid week and will join James Constable, Jake Wright and Jon Meades on the treatment table.
Matty Brown is still recovering from a hamstring injury and will not be available for selection against Oxford United.
Nathan Smith is suffering from a recurrence of his ankle injury that kept him out of the closing stages of the 2012/13 campaign and will not feature on Saturday.
Speaking to oufc.co.uk, Wilder said: "I have watched them two or three times, saw them in pre-season, and they are full value for their position."
"You can either be intimidated by their start or you look at it as a big challenge. I know I have players in my changing room who will roll their sleeves up on Saturday and want to show that we are there on merit and want to try and close the gap."
"We are the leading goalscorers in the league, they have had the most wins in the league and it all sets it up for a cracking game."
“The manager is a solid guy, he’s a really good fella, he knows the game, he knows the division and he’s assembled a really good squad."
“It is first versus second on paper but I think as a League 2 fixture Chesterfield versus Oxford would always be a big game no matter where the two teams are.”
Dean Czerwionka - aged 34 - Devizes, Wiltshire
"The Spireites have a tricky away game at the Kassam Stadiam where Oxford United are also flying high in the league two promotion stakes, previous encounters have been tight where the score could of gone either way, I travel to every game at Oxford as it has a wonderful family feel at the stadium and it's always a great day out.
The Spireites only ever seem to score one goal at the Kassam stadium as Oxford have made it a real fortress.
This season with the strength and depth in our squad that Paul Cook has put together I believe that the Spire boys have what it takes to knock Oxford united down a peg or two as we extend our dominance at the top of the league with a 3 - 1 victory because WE ARE TOWN."
Oxford United: 17/10 Draw: 12/5 Chesterfield: 6/4
Skybet have Chesterfield as slight favourites going into Saturday's game but believe the home side have every chance of taking the three points.
