Glentoran Football Club is a semi-professional association football club in Northern Ireland playing in the NIFL Premiership. The club was founded in 1882 and plays its home games at the Oval in east Belfast. Club colours are green, red, and black. The club's current manager is Eddie Patterson. Linfield and Glentoran are nicknamed Belfast's Big Two, as they have traditionally dominated local football in Northern Ireland since the demise of Belfast Celtic. The two play a league match on St. Stephen's Day each year, which regularly attracts the largest attendance of the Irish League season. Glentoran have other rivalries with two of the North Belfast clubs, Crusaders and Cliftonville.
