Born in Lagos, Sunny began his career in Nigeria with FC Ebedei and Jegede Babes. In 2003, he participated in two youth championships in Sweden and Spain: in the latter he appeared in Madrid's third edition of the Annual Immigrants World Cup, where he impressed so much he was given a five-year-contract with Polideportivo Ejido, in the second division.
Sunny became a regular player for the Andalusia team, making 65 competitive appearances during his two-year spell and signing for Valencia CF in the summer, but after one season where he was scarcely used, he was loaned to fellow La Liga club CA Osasuna. In late January 2009, he was linked with a move to England's Portsmouth, but the deal eventually collapsed due to financial complications.
On 30 June 2009, after a season which was marred by injury, Sunny was loaned to Real Betis for one year with a view to a permanent four-year move. He also appeared rarely during the second level campaign, as the Verdiblancos failed to return to the top division (seven matches out of 42).
In July 2010, Sunny had a trial in England with newly promoted Premier League side Blackpool, playing in a pre-season friendly against Crewe Alexandra on 27 July and four days later against Bristol City, but nothing came of it.
Sunny spent the first months of the new season training on his own, having been deemed surplus to requirements by Valencia manager Unai Emery. On 19 January 2011 he was again loaned, moving to CD Numancia from the second level.
In the following two years, still in that tier and already as a permanent signing, Sunny was first-choice for the Sorians. On 11 May 2011 he scored his first goal as a senior, netting the 2–1 winner away against Albacete Balompié.
Bnei Sakhnin / CSKA Sofia
On 30 July 2013, Sunny signed a two-year contract with Israeli club Bnei Sakhnin FC. On 3 January of the following year, he moved teams and countries again, joining Bulgaria's PFC CSKA Sofia after penning a two-and-a-half-year deal.
Real Salt Lake
After starting out the season in Turkey with Alanyaspor, Sunny joined Real Salt Lake on 21 January 2016. He scored his first Major League Soccer goal on 12 March, helping to a 2–1 home defeat of Seattle Sounders FC.
Sunny was released by Real Salt Lake following the 2018 season.
Sunday, who was born in Nigeria, was eligible to play for Spain under FIFA rules allowing players with dual nationality and without full international caps to switch allegiance before the age of 21. After first appearing for the under-19 side, he was called up by his adopted nation to the 2007 FIFA U-20 World Cup in Canada, playing in four games as the team exited in the quarter-finals.
