After securing the club’s return to the top flight for the first time since 2007, Wilder was handed a new three-year deal in July and was named LMA Manager of the Year.
In a statement on the club’s official website, Wilder said: “Naturally, I’m delighted to sign a new deal until 2024 and commit to the club that is close to my heart.
“I am grateful to [Sheffield United’s owner] Prince Abdullah for taking the initiative and offering this contract, we’ve had a great few years and hopefully we can continue the upward curve. Let’s see how far we can go on this journey.”
Prince Abdullah added: “Chris has played an integral role in our recent and current success and we want him at the helm in the future, driving us forward, hence the new long-term contract.
