Watford boss Slavisa Jokanovic is shocked by their promotion to the Premier League.
Troy Deeney's 21st league goal of the season and Matej Vydra's stoppage-time strike saw Watford win 2-0 at Brighton, giving them the chance to seal automatic promotion if results fell their way.
Rotherham's 86th-minute equaliser against Norwich and Ross McCormack's injury-time winner for Fulham against Middlesbrough saw Watford promoted, cueing wild scenes of celebration from their players on the coach home from Brighton.
Former Chelsea midfielder Jokanovic beamed: "It's incredible. I'm very, very happy for my players, for my staff, for the people that work in the kitchen and for our supporters.
"I'm a little surprised because I didn't expect everything to be all over today. We made a great job of it and many people around me helped me so much.
"The players did a great job and the supporters helped us and believed in the possibility of us getting promoted.
"The Championship is a crazy competition and many things can happen in the last five minutes like it did today."
