Mikel Arteta was all smiles after overseeing our fourth successive win, and was quick to highlight the contribution of his goalkeeper in the 2-0 victory over Newcastle.
Bernd Leno played his first-ever FA Cup match, and made a crucial save from Andy Carroll in the 90th minute to send the game to extra-time.
It laid the platform for us to go on and score twice in the final ten minutes to book our place in the fourth round.
"We had to patient," the boss said at full-time. "They are a team who are well-organised and make it hard for you. We had the chances I think, very big chances to score much earlier but when you don't do that, the game is open.
"If you don't do that in your box, you need your keeper in a key moment - like it happened after the corner kick on the counter - to save you.
"Bernd did it in a magnificent way and at the end we scored two and deserved to go through."
It means Arteta has won all seven FA Cup matches he has taken charge of, but it's back to Premier League action on Thursday.
"Let's go game by game and see who we get in the draw.
"It's great to keep the momentum going, to keep winning and keep the boys' confidence high. Now we have Palace, five days to prepare, let's go for it."
