Aston Villa star John McGinn wants his team to be more clinical in the future.
The Villains were unable to get all three points in a 0-0 draw against West Ham United on Monday night.
They had chances to take the game by the scruff of the neck, but had to settle for a point.
And McGinn knows they must do better in such games in the future.
He said to the club's official website: "The feeling is disappointment. You've got to take three points against 11 men at home, let alone 10.
"We got frustrated when they lost a man. They dropped deep and we gave the ball away a lot.
"We didn't create enough chances with the extra man. It's one that got away, definitely."
