Chris Wilder insists the Blades will continue to fight in the race for the Sky Bet Championship play-offs, following Saturday's stalemate with Millwall. Speaking after the draw at Bramall Lane, Wilder remarked: "The result didn't enhance our hopes of a top-six finish, but like I said to the players after they were down following the loss at Barnsley, the picture can change quickly. "This league is unpredictable, Burton, who looking like going down beat Derby, who perhaps should be in the league above." The Blades boss added: "Two weeks ago, Burton come so close to beating Middlesbrough, who equalised right at the death. "You just can't tip the results, but I'm frustrated and annoyed we're having to rely on others, saying that with three games to go our season is still alive and the players deserve credit for that."
