In his one full season at Ninian Park, the club narrowly avoided relegation to Division Three but did reach the final of the Welsh Cup, losing 2–1 to Barry Town. He was also named man of the match in the club's 1–0 FA Cup Fourth Round victory over Premier League side Manchester City in January 1994. During the following season, Aizlewood decided to leave the club in order to take up a player-coach role at Merthyr Tydfil. He later finished his career with spells at Welsh Premier League sides Aberystwyth Town and Cwmbran Town before retiring in 2000.
