Linked with a move to Manchester United in the early weeks of the summer, the England international has now committed himself to Villa Park until 2025.
In a statement to the club’s official website, Grealish said: “I am delighted to make this commitment to Villa. It is my club, my home and I am very happy here.
“The owners have made it very clear to me how ambitious they are and how they want to build Aston Villa. There are exciting times ahead and I am very glad to be part of it.”
CEO Christian Purslow added: “Jack is an emblem of our owner’s vision for Aston Villa. He joined our club as a local boy aged six and has developed into one of the country’s finest players finally becoming a full England international last week.
“We are determined to build a top team around him and are delighted that he is extending his contract and committing himself to the club he loves.”
