However, Deeney, much to the delight of the home fans, had the resulting spot-kick saved by Cech.
"They all just backed off. Yes, it plays a part".
Cech also dived low to his left to keep out a header from the Brazilian in stoppage time as Watford finished the first half the stronger, and they continued this momentum into the second period only to be hit by a sucker-punch. Then we had the chance to score the penalty - but we missed.
After a hard Thursday night game, on Sunday morning we still had the spirit to stick together.
Along with Cech, Gareth Barry is the only other active Premier League player on the list, sitting sixth with 181 clean sheets.
West Brom goalkeeper Foster: I feel sorrry for Pardew
Pardew criticised his players after the game for failing to fight until the end, but Foster has sympathy with the head coach. I made it very clear to him on the bench I'm not accepting that. "He's a player on loan who should show respect".
"He had to wait a while to save a penalty, and it's quite fortunate that it's against Deeney", added Wenger. 'In two weeks his situation shows how football is: in one week, he went from hell to heaven'.
After Shkodran Mustafi's early goal, Watford grew into the game and applied concerted pressure to the Gunners defence at the end of the first half and start of the second.
Ozil beat the assists record previously held by Eric Cantona, who made it to 50 in 143 appearances for Leeds and Manchester United during the 1990s.
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. Shkodran Mustafi scored Arsenal's 1000th home Premier League goal.
The scoreline was flattering for Arsenal, which ended a three-game Premier League losing streak, but Watford only had itself to blame after spurning multiple chances, most notably captain Troy Deeney's tame penalty.
"We had a very good first half", said Wenger.
