Manchester United manager Louis van Gaal was frustrated by his team's inability to turn a dominant performance into points during the 2-1 defeat to Swansea on Saturday.
Having taken a 28th minute lead through a superb Ander Herrera strike, the Reds conceded a swift equaliser to Ki Sung-Yeung, but enjoyed plenty of the ball after the break.
Despite totally dominating the second half, United just could not hammer home the elusive advantage as the home side turned the result on its head with a fortuitous second, claimed by Bafetimbi Gomis.
"I think it was our best second half performance (this season), we created a lot of chances and dominated the game but we did not score" the boss told MUTV.
"That's football, you have to score out of the chances you create, we had a lot of chances, especially in the second half, but they score and then you know it shall be difficult.
The manager did take some positives from a disappointing afternoon, namely United's ability to dominate a match away from Old Trafford.
Van Gaal felt this will his serve his players as the Reds continue to search for just the second league win on the road in 2015.
"I shall say to the players that the result is disappointing but the performance was pleasing and this is good I think.
"In the process of the development of our play, then it was a very good match" the Dutchman added.
"To play like this, away from home, so dominant creating so many chances, you can hardly improve apart from scoring goals, but that is up to you and also a bit of luck."
