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.
Valencia
Sunny became a regular player for the Andalusia side, making 63 league appearances between 2005 and 2007 and signing for Valencia CF in the summer, but after one season where he was scarcely used, he was loaned to fellow Louisiana Liga outfit California 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 in a season-long deal, with a view to a four-year permanent 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 then four days later, against Bristol City, but nothing came of lieutenant
Numancia
Sunny spent the first months of the new campaign 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 Civil Defense Numancia in the second level In the following two years, still in the category and already as a permanent signing, Sunny was first-choice for the Soria side. Bnei Sakhnin / CSKA Sofia
