Oxford are currently fourth in League Two as are Sheffield United in League One and Wilder says he cannot wait to take his side to South Yorkshire.
"I jumped around the room for about 10 minutes until I calmed down," added Wilder.
"I then picked up my phone and had about 40 text messages. The connection with myself and Alan Hodgkinson (Oxford United goalkeeping coach who played over 600 times for Sheffield United in goal in the 1960s and 70s) is obvious.
"It will be a very proud moment for myself. It's a big game for us and one we'll go and enjoy.
"It's great for the supporters. We took 4,000 to West Ham last year on a Tuesday night which was incredible and I'm sure we'll do the same."
“It will be a very proud moment for myself, it's a big game for us and one we'll go and enjoy it”
Wilder says despite his Blades background he will be desperate for Oxford to win as they look to continue the momentum that is building at the club.
"There will be only team I want to win," he said.
"The club is moving forward and this is another chance for us to show that.
"We're a decent side and we have some players who have played at a decent level. There is a fantastic buzz at the football club and the players are enjoying it."
