Sheffield United boss Chris Wilder has admitted frustration with their slow winter market.

Wilder was speaking ahead of today's clash with West Ham.

Wilder said: "I am, and we are, quite frustrated because we felt we could have got them in for the weekend. But the deadline was 12 o'clock today [Friday], so we've just missed out.

"But we've worked hard in identifying a couple of potential signings coming in before next week. I always knew it wasn't going to be a huge window in terms of numbers coming in. Two or three was our target and I believe we will reach our target. We've had to work hard as a football club to get them over the line. And hopefully we'll get the rewards for a lot of hard work that's gone into getting the players we want.

"Really close. We've worked extremely hard at identifying them. It is a difficult window to work in. There hasn't been a great deal of business at the top end. Identifying players and loans as well. I think we all understood there weren't going to be any permanent ones and if they were they'd be really good deals.

"We've worked hard to strengthen the group and we believe when the window shuts that the group will be a lot better. There will be a feel that we will be in a better position than when the window opened. We're cracking on with it, 24/7, and everyone's enthusiastic and committed to making it stronger and better."
