Gavin Rose, manager of Ryman League Premier Division club Dulwich Hamlet, has added to his squad with the signing of 20-year-old Michael Onovwigun.
An imposing midfielder, Clapham-born Onovwigun signed for Chesterfield from Brentford two years ago and made two first-team appearances for the Spireites while also spending time on loan with Sheffield FC, Stalybridge Celtic and Gateshead.
Onovwigun began his career in the academy at Brentford, signing scholarship forms in the summer of 2012. After featuring regularly for the development squad in friendly matches during the summer of 2012, Onovwigun made over fifty appearances for the youth team and nine for the development squad between 2011 and 2014.
He departed the club at the end of the 2013/14 season after failing to be offered a professional contract.
In the summer of 2014, Onovwigun signed a one-year professional contract at League One side Chesterfield after a successful trial.
He received his call into the first-team squad in August and made his League debut when he came on as an 89th-minute substitute in a 2-1 win.
Onovwigun finished the 2014/15 season with three appearances and the option to extend his contract was taken up for another season.
He made his sole appearance of the 2015/16 season as a substitute during a 3-1 Capital One Cup defeat to Carlisle United in August 2015 and was released at the end of the campaign.
Onovwigun joined Evo-Stik Northern Premier League First Division South side Sheffield FC on a 28-day loan in November 2014 and the deal was later extended until January 2015.
The following month, Onovwigun signed on a month`s loan for Vanarama National League North side Stalybridge Celtic but he made only one appearance.
In March 2016, Onovwigun joined National League side Gateshead on loan until the end of the season and made three appearances before returning to the Spireites at the end of the season.
