The Premier League side eased past Freiburg 3-0 to secure their first piece of silverware since 1996.
It’s also Emery’s first trophy since taking over in 2022, and his fifth Europa League as a manager having won three with Sevilla and one with Villareal.
Speaking to TNT Sports after the game, Watkins was full of praise for his manager, describing his feelings as… “indescribable.”
"Amazing, amazing. To perform like that was unbelievable. I felt like we really controlled the game and we punished them in the end,” he said.
On the goals Villa scored: "I've watched many finals and I think set pieces are crucial. Until then it was a bit cagey, they were going man for man.
“Fair play to (set piece coach) Austin MacPhee for having the courage, we left four up on a corner.
"An unbelievable experience. Look at this. It's what you dream of."
On what it means to win the trophy: "Sometimes you have ups and downs but we pulled through in the end, we pushed on, we got Champions League football. It's so special. All of these fans - it's indescribable."
On Unai Emery: "He was really calm today in the build up. Sometimes in league games he's anxious because he wants to get the win but today he was calm and that set the tone for us boys.
“Youri (Tielemans) ran the show in the midfield. And Victor (Lindelof) has done so well since he's come in, he was my player of the match today."
