Burnley captain Josh Brownhill, who scored both of his team's goals against Sheffield United, said: "I'm speechless. All that hard work this season.
"We've been written off so many times, people calling us boring. We've bored our way to the Premier League.
"It takes a whole team. It's not just a back four, a goal keeper, it takes everybody. I don't think a lot of the lads will sleep. I'm so buzzing for the lads that haven't played Premier League football."
