Sheffield United boss Paul Heckingbottom admits his team selection didn't work after defeat at Burnley.
The Blades were hammered 5-0 on the day.
Heckingbottom said: "We picked a team with experience, physicality to impose ourselves on Burnley, which they would have been expecting.
"And then we dangled two legs in two tackles in the first 30 seconds and we're 1-0 down. The second goal's not much better from our point of view in how we defended and by half-time we're down to 10 men.
"Burnley would not have been expecting a game like that, and neither was I. That's decided the game."
