Javi Gracia's side ended a seven-game winless run by beating Newcastle United 2-1 last weekend but it is another campaign which will end with a sense of regret for the Hornets.
Although Watford can finish as high as tenth if results go their way, they will rue a dismal middle third of the season which saw head coach Marco Silva courted by Everton. The team's form nosedived and the Portuguese coach was sacked in January.
Still, a fourth season of Premier League football has been secure for some time now and Gracia will hope to catch José Mourinho's side off-guard as the Red Devils prepare for an FA Cup final against Chelsea at Wembley next Saturday.
Long-term absentees Tom Cleverley (hamstring), Nathaniel Chalobah (fractured knee), Younès Kaboul (fractured metatarsal) and Tommie Hoban (ACL) are all sidelined.
André Carrillo (groin) and Stefano Okaka (thigh) are both doubts for the game at Old Trafford.
