Stuart Attwell has replaced Uriah Rennie as referee for tomorrow's televised clash between City and Derby County.

The 25-year-old is the Premier League's youngest referee, having been appointed by chief Keith Hackett after just one season at Football League level.

Attwell, from Nuneaton, replaces Rennie for tomorrow's game but will still be assisted by Steve Rubery (Essex) and Andy Williams (Herefordshire). The fourth official is Andy Penn (West Midlands).
