Bristol City have signed Brighton defender Hayden Roberts on a three-year contract.

The 21 year-old moves to City on a free transfer.

"It's a big moment in my career to come to a club like Bristol City, to kick on and progress both individually and with the club," he said in a club statement.

"I want to be a winner and win with Bristol City, and to help the club get to the heights they want to - I can't wait for the challenge ahead."

Roberts spent last season on-loan with Derby County.
