Bristol City have appointed Richard O'Kelly as assistant manager after reaching a compensation deal with Walsall.
O'Kelly was working as No 2 to Dean Smith at the Banks's Stadium but will now resume a partnership with City manager Sean O'Driscoll which yielded promotions at Bournemouth and Doncaster.
O'Driscoll told the club website: "Richard is an excellent coach whose opinion I respect and has the sort of character that every football club needs.
"He will bring enthusiasm and positivity to everything he does and I'm delighted he has joined me as I know it was a tough decision to leave Walsall, where he was achieving great success on a limited budget."
City's football managing director Jon Lansdown said: "We're delighted to welcome Richard to the club as he links up with Sean again.
"They've worked together well in the past, building up clubs and achieving success at the same time."
