The England Under-21 global made just his sixth Premier League start of the season in place of Laurent Koscielny with Arsenal keeping a first top-flight clean sheet since December 16.
Afterwards Arsène Wenger spoke to Arsenal Media about continuing the momentum from Thursday's Europa League win over Milan.
"That's my celebration since I'm young and yes that's it I'll do it all my life".
We knew we're on a hard run at the moment, we had to look at ourselves and we had a big result in midweek in Milan and I felt we carried the determination into today.
But Deeney, who had scored three times in his past four appearances, had a day to forget on Sunday as his penalty was too close to Cech in the middle of the goal, and the Czech saved it. "It is not easy".

Hollywood also never quite looked at her the same way either. "I felt the need to make myself whole". We are so different from one another, but we share the same values-we're totally two peas in a pod.
Aubameyang believes he is now getting towards his best and is keen to keep it up to help relieve the pressure on Wenger, who has seen his position come under scrutiny following a recent run of damaging defeats.
Watford took off Femenia and replaced him with Will Hughes, and moments later Arsenal could have had a penalty when Adrian Mariappa clattered Mkhitaryan as he crossed but the referee waved play on as the ball just eluded Aubameyang in the middle. An early goal from defender Mustafi and the goals from the fabled duo of Aubameyang and Mkhitaryan was enough to secure the three points for the Gunners. "I am really happy because I am here because of him". He also added,"I think I've shown in 22 years that I can do that, and that I respect everybody's opinion and I focus on my job with total commitment". It may have been becoming a coach myself that makes me feel differently.
This is not the first time there have been a wealth of empty seats on display recently, however, with Arsene Wenger's men's last home outing - a 3-0 defeat to Manchester City - also failing to draw in the crowds.
After scoring in a 3-0 victory over Watford, he told reporters: "It was a big win".
"You are 4-0 up and conceded late goals".
