Sheffield United must do more if they are to survive in the Premier League this season.

That is a view the club's manager Paul Heckingbottom admits to after their opening game.

The Blades were beaten 1-0 at home by Crystal Palace, but know they could have lost by many more goals over the weekend.

“We've sold players and now we've got a bit of money, so we'll spend it," the Blades coach told reporters post-game.

“The best way to put it is that we only had six lads starting who played the game that got us promoted.

“We've lost all the goals and assists and how we look to win the ball back at the top end of the pitch, so our identity as a team has gone.

“All I'm bothered about is replacing that or we'll have to change the way we play a bit."

“It is a big difference in terms of level," added Heckingbottom.

“You could see that certainly at the top end of the pitch, their quality was there. They had the cutting edge even when we defended it pretty well. We had youth at the top end and lacked that cutting edge. That's just where we are right now."
