Watford has been promoted to the Premier League after being relegated from the top flight just nine months ago.
With a 1-0 victory over Millwall on Saturday afternoon, the Hornets clinched the second automatic promotion spot, following in the footsteps of Norwich City.
In the 11th minute, Ismaila Sarr was brought down in the box and converted a penalty to score his fourth goal in five games and lead Xisco’s side to victory.
Watford can still retain the Championship title with two games left to play, but they will need Norwich to lose both of their remaining games to do so.
The Canaries won 3-1 against Queens Park Rangers on Saturday to keep their five-point lead at the top of the table.
Promoted teams so far:
- Norwich City
