Arsenal boss Arsene Wenger hails his side's "resilience" as they beat Queens Park Rangers 2-0 at the Emirates.
Chile's Alexis Sanchez missed a penalty in the early stages of the game but bounced back minutes later as he headed Arsenal's first in the 37th minute.
Tomas Rosicky added a second in the 65th minute before Charlie Austin's converted from the spot for the visitors to pile pressure on the Arsenal defence.
But the Gunners worked hard in defence in the final part of the game to take all three points and hold on to sixth place in the table.
"We made it hard for ourselves but we played two [types] of games," Wenger said.
"[The first] one where were in control of the game until it went 2-1. After, you never know. The last five minutes were a bit edgy because we conceded a late goal last week and you could feel that was a bit in our mind.
"But overall I think we were in control for big parts of the game and in the end we have shown resilience and fortunately got the three points.
"We were nervous [in the last ten minutes of the game] and the opponent pushed forward. Our game is [about] psychology and the mental aspect. In the final part of the game when the result is not settled, it's always very important."
Striker Olivier Giroud was shown a straight red for headbutting Queens Park Rangers's Nedum Onuoha in the second half and the Frenchman admits the referee took the right decision.
"It was a deserved red card," added the Frenchman.
"Madness is a strong word but he didn't kill him, he touched him and should not have done it. He should have been in control. Olivier Giroud knows he made a mistake and I know him well enough to think that he will not do it again.
"He told me he was pushed in the back and that projected him into the keeper. Maybe because the injury he had still plays a part on his mind and it's unusual for him. Usually he's a guy who's in control of his response."
