Manchester United goalscorer Mason Mount conceded frustration after their 1-1 draw with Brentford.
Kristoffer Ajer canceled Mount's 96th opener three minutes later for the Bees to earn a more than deserved point.
Mount said: "When you go 1-0 up right at the end you want to try and hang onto that.
"If you look at the game overall it wasn't to our standard. We know that. When you score at the death you think you can maybe hang on. But maybe we didn't deserve it.
"Brentford make it difficult. It is never easy coming here. They make it tough and get around you. Maybe we didn't get it going from the beginning.
"We know we can improve and we need to because we need to win games. We will improve, we will work hard.
"These are the games you want to win. We need to step up and that is what we will focus on."
