MLS club DC United have foregone the option to re-sign four players for the 2011 season.

The Washington club will not exercise options on defenders Barry Rice and Juan Manuel Pena, as well as midfielders Brandon Barklage and Carlos Varela.

37-year old Pena struggled with injuries in 2010 and managed just ten appearances, Rice was only seen twice in MLS play after arriving from University of Kentucky, Barklage played just seven times in two seasons whilst Varela made six appearances after joining from Swiss club Neuchatel Xamax in September.
