Sunday began his career in
Poland with
Szczakowianka Jaworzno, where he made 15 appearances, scoring once, before moving to
Lithuania to play for
FC Vilnius in 2006. During his time in Lithuania, he made 27 appearances, scoring 3 goal, before deciding to try his luck in
England in 2007, signing for non-league
St Albans City. He impressed at
Clarence Park, bagging 3 goals in 13 appearances before pitching up on trial with
Colchester United on trial during the summer of 2008, where he eventually earned himself a one-year deal. A pacy and powerful striker, Akanni-Sunday Wasiu joined
Luton Town on a one-month loan in mid-January 2009, having been a long-term target for Hatters boss
Mick Harford. He scored once in five games for Luton before his loan deal expired. After the 2008–09 season, Wasiu was released by Colchester after failing to make an impression on the first team. Sunday joined
Floriana on 28 August 2009; his debut came the following day in a 0–6 loss against rivals
Valletta. His second appearance for the club was a more pleasant experience, as he netted his first goal in the 1–1 draw against
Tarxien. The powerful striker fast became a fan favourite at the club and was voted as the Man Of the Match on three occasions by the Maltese journalists. In 13 matches with the Greens' Wasiu netted no less than 7 goals. For the 2010 season, Wasiu joined Chinese side
Changsha Ginde before moving to
Shenyang Dongjin in 2011. In 2012, he returned to Floriana. In September 2014, he returned to England to play for
Whitehawk.

Malaysia Premier League club
UITM. There, he scored a total of 20 league and nine cup goals.
