Watford striker Tommy Smith claims the resurgent Hornets can still avoid relegation from the Premiership.
The league's basement boys have been given heart by two victories - over Blackburn Rovers and West Ham - in their last four Premiership games to close within seven points of safety.
"There are still a lot of points to be won, and our character is our big asset going into the second half of the season," said Smith.
"All you need is a little break with the fixture list, have two or three winnable games together, and you can suddenly be among the pack again, which is what Sheffield United achieved.
"We believe we can do that. We have a squad of players who won't give up, and we will fight for our lives."
Meanwhile, the Hornets have received a double boost with the news that injured duo Clarke Carlisle and James Chambers both stepped up their returns with successful outings for the reserve team in midweek.
Clarke has been sidelined all season with a serious thigh injury, while Chambers is still recovering from an ankle problem sustained against Newcastle in December.
