Argentinean Armenian tennis player David Nalbandian for the first time after a long treatment in December will take part in an international tournament in Buenos Aires. The main contenders of Nalbandian in the tournament will be an Argentinean tennis player Juan Monaco and Spaniard Carlos Moya.

Buenos Aires is the first major test after long treatment for Nalbandian. Recall that Nalbandian took a course of rehabilitation after surgery on his hip in May 2009.
