Mikel Arteta thinks Arsenal lost two points in Tuesday's 1-1 draw with Leicester City.
The Gunners had a couple of a chances to double their lead in the first-half after Pierre-Emerick Aubameyang's opener.
Jamie Vardy would eventually equalise with six minutes remaining, and Arteta says his side must learn to "kill" games off.
"We lost two points. I think we deserved to win the game," the Spaniard said.
"But when you have the chances you have to kill them. Three or four-nil and the game is over. We had to play a long time with 10 men.
"It is where we want to head. I am really proud because a lot of things we worked on happened, the players are believing in the way we want to play, how aggressive we want to be. Just that little extra quality to finish the actions better.
"The boys played really well credit to them. I am so proud. We take the positives, keep improving and go again against Spurs and try to win."
