A pacy and powerful striker, Akanni-Sunday Wasiu joined Luton Town on a one-month loan in mid-January 2009,^[3] 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.

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.
