Arsenal manager Unai Emery praised his side's patience in overcoming an "organised" Watford side that for large parts of the game frustrated their hosts.
An own goal by Watford centre-back Craig Cathcart gave the Gunners the lead before Mesut Ozil, notably quiet for most of the match, fired home from Alexandre Lacazette's cross. Arsenal went on to win the match 2-0, making it five straight wins in the Premier League.
"We knew before the match it would be difficult," said Emery speaking to football.london. "We needed to be competitive in the moment with Deeney, we needed to defend well with him on the second action.
