Jack O'Connell says Sheffield United will not be intimated facing Manchester United this weekend.
The Blades have surprised many this season and currently sit in fifth place on the Premier League table.
The defender said: "The next game is always the biggest game of the season and Manchester United is a massive club, with a rich history.
"They have some very good players, internationals all over the pitch, and we're expecting a tough game. But we'll be going in it trying to win.
"For a lot of players, it's their first time playing at big stadiums and against these teams but I don't think the occasions have got the better of us. We've performed, and hope to do the same in the near future."
