Barnsley boss Poya Asbaghi can't hide disappointment after defeat to Derby County
And Asbaghi admitted: "It's a big disappointment for us, we knew the importance of this game and over 90 minutes we have to play better than we did today.
"Derby started the game better than us but our reaction after the first goal was pretty decent and we got into the game more and more in that half and we felt confident of doing better in the second.
"But then we lose the ball in a vulnerable position and they score a second and that's mentally really tough in this arena and put us in a situation that in the end was too difficult to overcome.
"Overall what needs to improve is the ability to move the ball even faster. Our decision-making and winning second balls has been much better than we showed today."
Morrison struck the top of the bar in the 32nd minute with a shot from the edge of the box and gave Derby a two-goal cushion two minutes into the second half.
Callum Brittain allowed the ball to slip under his foot and Lawrence went through to rattle the bar with Morrison driving in the rebound.
