The Hornets have achieved their goal of securing top-flight football for next season, but they are also licking their wounds after losing at Wembley last weekend.
Watford's hugely impressive first half of the campaign means that they were able to go for it in the FA Cup, reaching the semi-finals before going down to Crystal Palace on Sunday.
Yannick Bolasie's early goal put Palace in front before Watford hit back through captain Troy Deeney, but the Hornets were level for just five minutes as Connor Wickham's header restored the Eagles' lead and sent them through to a repeat of the 1990 final against Manchester United.
After seeing off defending champions Arsenal away from home in the quarters, it was a disappointing way for Watford to go out and now they will want to end the season on a high after a disappointing 2016 half of the campaign.
The Hornets have won 13 points from their last 17 Premier League matches (W3 D4 L10), compared to a tally of 28 in their first 17 games of 2015-16 (W8 D4 L5).
At home, they are without a win in five league games and this downturn in form has led to speculation over the long-term future of manager Quique Flores.
The Spaniard has confirmed that there is an exit clause in his contract this summer and further fuel was added to the fire when Swansea City boss Francesco Guidolin admitted that he has a good relationship with the Pozzo family who own Watford.
Top-scorer Ighalo, whose father passed away shortly after Watford's semi-final defeat, has struggled badly in recent months after bursting onto the Premier League scene in the first half of the year.
The Nigerian has averaged a goal every 1,200 mins in the Premier League since the turn of the year (1 in 1,200 mins), compared to a goal every 122 mins before January 1 (13 goals in 1,591 mins).
One man who is impressing still for Watford is goalkeeper Heurelho Gomes, who needs one more clean sheet this season to equal his best-ever tally in the English top flight (12 for Tottenham Hotspur in both 2008-09 and 2009-10).

The Villans are going down with not even a whimper. They enter this match on a 10-game losing streak now 14 points adrift at the foot of the table.
Last weekend they managed two goals for the first time in 11 matches, but they were still resoundingly beaten as Southampton put four past them at home.
Former Leicester City boss Nigel Pearson remains the odds-on favourite to take up the manager's job full time this summer, but Ian Holloway has said that the Birmingham-based club should consider wily Ipswich Town boss Mick McCarthy.
Away from Villa Park, the Villans have failed to score in five of their last six matches.
Recent form: LLLLLL
With just one real injury concern out of the cup defeat to Palace last weekend, Etienne Capoue will miss out with a knee injury. Ighalo, however, is expected to play despite the loss of his father.
Rudy Gestede has been used as an impact sub in recent weeks but will hope for a chance to start at Vicarage Road.
Watford possible starting lineup:
Gomes; Nyom, Britos, Cathcart, Ake; Guedioura, Suarez, Watson; Deeney, Jurado; Ighalo
Villa possible starting lineup:
Guzan; Hutton, Clark, Lescott, Cissokho; Sanchez, Gueye, Westwood; Bacuna, Ayew, Sinclair
Head To Head
Watford will be looking to secure two league wins in a single season against Aston Villa for the first time since 1969-70 having won 3-2 at Villa Park in November.
That defeat ended a run of four straight clean sheets against Watford for Villa, whose record in Hertfordshire is not the best.
Watford have lost just one of their previous eight league meetings against Villa at Vicarage Road (W4 D3 L1).

With desperate Newcastle United and top-four side Arsenal to come, this is probably the visitors' last chance to add to their measly points tally of 16, but there is no reason to believe that they will.
