Watford secured promotion to the Premier League on Saturday with two games to spare, after a 1-0 win over Millwall in the Championship at Vicarage Road.
Ismaila Sarr's 11th-minute penalty proved enough as Watford guaranteed one of the two automatic promotion spots alongside Championship leaders Norwich City, who booked their top-flight spot last weekend.
Xisco Munoz's Watford have secured an immediate return to the top flight -- which has been worth at least £160 million ($221.3m) in previous seasons -- having finished second-bottom of the Premier League in the 2019-20 campaign.
Watford were one of the playoff contenders after a mixed start to the second-division campaign but found another gear when Munoz replaced Vladimir Ivic as manager in December.
The Spanish manager has guided Watford to 17 wins in 24 Championship games, opening up a 10-point gap over third-placed Brentford, who have a game in hand.
Watford's victory means Norwich must wait to be crowned champions, despite a 3-1 win over Queens Park Rangers.
Daniel Farke's side need two points from their remaining two games to guarantee the second division title.
