Since beating Barclays League leaders Leicester City in mid-February, Arsenal have won just once in the league in four games, the 2-0 victory at Everton last time out.
That poor run leaves the Gunners 11 points behind Leicester and six behind Tottenham Hotspur, who are second.
Watford have kept only two clean sheets in their last 13 Premier League games but on March 13 they won 2-1 at the Emirates in the FA Cup quarter-finals to set up a Wembley semi-final against Crystal Palace.
That was Watford's first win at Arsenal since 1988, when they won 1-0 at Highbury in the old First Division.
Since then, Arsenal have won five out of five in the league against the Hornets, most recently the 3-0 victory at Vicarage Road in October, with goals from Alexis Sanchez, Olivier Giroud and Aaron Ramsey.
Watford arrive on the back of three straight defeats, a run which has seen them drop to 14th in the Premier League and just 11 points clear of the relegation zone. One more victory should assure Watford of their Premier League place but they have won only five times away from home in the league, most recently at Crystal Palace in February.
Arsenal are still without Santi Cazorla, Ramsey, Tomas Rosicky and Jack Wilshere. There is a chance that goalkeeper Petr Cech can return after a five-match absence caused by a calf injury. Mathieu Flamini is another to have to go undergo a test.
Watford, meanwhile, are still missing Joel Ekstrand, Rene Gilmartin and Tommy Hoban.
