However, Deeney, much to the delight of the home fans, had the resulting spot-kick saved by Cech.
Cech registered his 200th Premier League clean sheet, the first goalkeeper to achieve this feat in the competition's history.
"His [Cech's] situation shows how football is, in one week he has gone from hell to heaven". In one week he goes from hell to heaven, and that's how life can be. But overall the spirit and desire was good.
"You need to work a lot to try and beat this kind of team", the midfielder told Watford's official website.More news: Who is Nikolai Glushkov? Putin enemy found dead in London TODAY
Over his years of service for the Blues, Cech collected several records in quick fashion before passing the torch to young keeper Thibaut Courtois in his last season at Stamford Bridge, leaving SW6 as a Premier League and League Cup victor to then join Arsenal in the summer of 2015. "And yes I feel a little sad", the 28-year-old said. "When you look what he has achieved, consistency is always the most hard in life".
What made the achievement that much more special though is the fact the Germany worldwide became the fastest player to reach 50 assists in the English top-flight, taking just 141 games to get there and, in doing so, breaking the record previously held by Eric Cantona (143 games).
"Maybe the world has changed as well", Wenger added.
"Of course I am really happy (for Wenger) because I am here because of him".
The Gunners were coming off the back of a trip to Italy where they had beaten AC Milan 2-0 in their Europa League match on Thursday and Arsene Wenger would have been hoping his side could carry that momentum with them. "When I was in Dortmund, I was playing every three days but now I play once a week or have a long time between games".
Shkodran Mustafi has come in for vast amounts of criticism in recent weeks but his performance at the back showcased a solid, composed defender who isn't shy of going up for set pieces.
