Manchester United midfielder Juan Mata has claimed that it is vital that he and his teammates learn to maintain their advantage when they take the lead in matches.
On Sunday, Mata opened the scoring for Louis van Gaal's side in the second half against Swansea City at the Liberty Stadium.
Within five minutes, the Swans took the lead and eventually won the game 2-1 to inflict United's first defeat of the campaign.
In his weekly blog, Mata wrote: "To be honest, I keep thinking about the game and that we weren't able to seal the three points after the positive start of the second half. Our intention was to close a good week in the best possible way, with another victory ahead of the international break, but we weren't able to do it.
"We must learn from games like this, once and for all, and know how to maintain a positive result when we take the lead."
Meanwhile, United are said to be on the verge of signing Monaco forward Anthony Martial, who is travelling to Manchester to seal a reported £36m deal.
