Keith Bertschin was one of my favourite players when I first started supporting the Canaries. I remember his two goals in the 5-1 thrashing of Birmingham City on 8th September 1982. He joined Norwich City in August 1981 from Birmingham City having earlier begun his career at then non-league Barnet and Ipswich Town. In 138 appearances (including two as substitute), he netted 38 goals for the Canaries. A regular in the City forward line, he formed a powerful partnership with John Deehan.

Joining Stoke City in 1984, he added another 88 appearances and 29 goals to his career record before moving North to Sunderland in March 1987. 36 appearances for the Wearside team generated only seven goals and a move to Walsall came just sixteen months later. He left the Saddlers for Chester City and then moved on to Aldershot Town in 1991. Aldershot's bankruptcy led to the termination of his contract and his professional career.

Since then, he has spent time in non-league football with Solihull Borough and Evesham Town. In 1994, he joined League of Wales side Barry Town and hit the winning goal in the Welsh Cup semi-final against Bangor. In 1995, he moved to Worcester City and then on to Hednesford Town and Tamworth. 1996 saw him join his sixth amateur side Stafford Rangers. He announced his retirement in February 1998 to devote more time to his business interests. He signed off in fashion scoring the winner against Wisbech Town.

Keith then became a licensed player's agent for First Touch Soccer Sports Agents. He returned to competitive football during the 2001/02 season, joining Steve Bruce, Mark Bowen and John Benson at Birmingham where he coaches their Reserve team

When Bruce left Birmingham to take charge at Wigan Athletic, Bertschin followed and is their Reserve Team Manager. He again followed Bruce when he took charge at Sunderland in June 2009.
