Manchester United midfielder Marcel Sabitzer was left frustrated after their 2-2 draw with Europa League opponents Sevilla.
Sabitzer struck twice to have United 2-0 ahead in this first-leg before Sevilla's fight back.
He said, "I have problems finding the right words. It was like a rollercoaster game. We had to finish the game off and at the end it's a draw and it's not what we wanted.
"We had the chances [to finish the game off]. We controlled the game but unfortunately we gave easy goals away. We cannot concede these kinds of goals and we're really disappointed now.
"In a competition like this you have to be focused until the end. The last minutes were a bit strange. Two stupid goals. That's not what we wanted. When you are 2-0 up at home you have to get it done."
