Sheffield United manager Nigel Clough has insisted that he still has work to do, despite guiding the club out of the League One relegation zone.
The Blades have not lost any of their last 10 matches and knocked Premier League Aston Villa out of the FA Cup last Saturday.
"We've been on a great run and we have to keep the same sort of form going," Clough told Sheffield United's official website.
"It sounds easy but the players have to keep working hard on the things that have served us so well. One defeat in 10 is a decent run and we find ourselves climbing away from the bottom four.
"We haven't achieved anything yet, we are only just above the bottom four so we have a long way to go yet. We want to get into that 'boring' mid-table, except it wouldn't be boring for us to get there."
United travel to Meadow Lane to face Notts County on Saturday.
