Fulham boss Marco Silva was left frustrated after their defeat at home to Manchester United.
Bruno Fernandes struck on 91 minutes for United's 1-0 win.
Silva later said, "It is difficult to believe but the reality is it did happen again against us. It is something we clearly have to sort out, we have to keep the emotional control to the end of the match.
"It was a very good game from ourselves. A balanced game but we had a very good second half.
"You have to be clear on the game until the last minute.
"We have to be more assertive and much more ruthless in these types of moments because we had clear chances to score. They had one dangerous cross in the second half, after that they didn't have anything.
"We played well, we put them under pressure, we were on the front foot. Our second half performance was a very good level but we go with this feeling again where we played well but didn't get anything from the game."
