Off the back of a 2-1 win over Charlton on Tuesday, Wilson is hoping his side can carry on that momentum into the Yorkshire derby.
"That's what it's about, momentum," said Wilson. "Prior to the game we were quite calm. We didn't harp on about how important the game was. They (players) were well aware and didn't need me to go all over it again.
The Whites visit Oakwell currently 16th in the league on 50 points, "I don't know if we could ask for a better one (match)," added Wilson. "It's not just a fixture for where we are in the table, it's a derby as well for the bragging rights and pride.
"They'll be wanting to get a run going and stabilise their situation."
As far as team news is concerned, Wilson is unsure whether Kelvin Etuhu (ankle) and Jack Hunt (hamstring) will make it back into the squad.
"Jim (O'Brien) came down with us to Charlton, he told me he was fit before the game but that's the type of character he is. He's not fit yet."
The Barnsley boss has called for his players to remain calm, whilst maintaining that competitive and creative edge.
"The one thing that's pleased me with the players is that we are just looking at the next game," added Wilson.
"The way the fans supported us. They have been fantastic.
"We've gone about business correctly and properly. As a group there's an arm around all of them. I think here's areas where we encourage them to do certain things.
"They all know what's required. What they're giving us is real grit and determination.
"We have to make sure we are ultra competitive but calm when it comes to taking our chances."
