Manchester United boss Erik ten Hag was unhappy with their finishing after defeat at Brighton.
A 99th minute penalty from Alexis Mac Allister saw the hosts triumph on the night just weeks after United had beaten Brighton in the FA Cup semifinal penalties.
Ten Hag said, "We have to be more clinical on our chances we produced in the first half. In the end we gave away a goal and that can't happen. It was also a little unlucky because it was never a free kick from where the corner came from but then you can't bounce back anymore and that is what we have to do on Sunday.
"We had the chances clear. Great opportunities, one has to be in."
Asked about their goalscoring, he continued: "I don't have concerns. It is about keeping the focus. Don't lose the focus, then we take that point. In the end if you can't win it because you don't finish the chances then don't lose.
"It is handball, maybe he is out of balance or maybe got a push in the back. My anger is more about the free kick before the corner, it was never a free kick. There were so many bad tackles tonight.
"It is not about the officials, we have to finish the chances, be more clinical and don't make the mistakes we did like in the last seconds.
"We have everything in our hands and we have to bounce back. We take the lessons from tonight and we have to move on."
