Chris Wilder insists Sheffield United must believe they can beat flyers Aston Villa

The bottom-placed Blades have not tasted victory away all season and face a tough trip to Villa Park, where Unai Emery’s side have won their last 15 Premier League games.

Villa have surprised many with their level of performance this term and will move top of the table with a win tomorrow

Wilder told a press conference: “They’ve had 15 wins out of 15 at home so always a tough place to go.

“They’re on a fabulous run and an incredibly well coached team with outstanding individuals and an opportunity for them to go top of the division Friday night.

“There’s a lot of issues we’ve got to solve on the night but as we talked about it’s no good getting on the bus if you don’t believe or have confidence in your ability or your team’s ability to go and get a result and that’s how we must approach the game.

“(Emery is) a world-class operator with what he’s achieved and won in Europe and the standing he has in the game and put that work in Villa really quickly and the majority of us are not surprised in terms of the effect the manager has had on that team.”

Wilder has won one of three games in his second spell in charge of Sheffield United, who are six points from safety.

“They’ve been battered and bruised, it’s been a difficult first part of the season,” Wilder added. “They’ve shown enough life to me in the last three games that there is something in the season for us. We have to keep that going and hopefully they can keep on that upward trajectory they are showing me and more importantly the supporters.

“We’ve got to keep improving and we are learning on the job in the hardest league in the world.”

Sheffield United have been hit with injuries throughout the first part of the season, with Chris Basham, Rhys Norrington-Davies, John Egan, Tom Davies and Rhian Brewster all currently sidelined.

Wilder admitted his side are far from full strength but does not want to use it as an excuse.

He said: “You want your full and strongest hit to go to Villa Park because it’s what you need and we are not going to have them.

“It still is a young, inexperienced and naive group, but as I said no excuses. We go there and no matter what group we pick we fully expect and demand a committed and together performance because if not you get pulled apart at places like Villa Park.”
