United introduced Brazilian newcomer Fred midway through the second half to hand him his debut against top Mexican outfit Chivas at the Estadio Jalisco.

However, according to DC's own website, "the reigning Australian league MVP saw little of the ball and was a non-factor around the goal."

The Americans were beaten 2-1 on the night to exit the tournament 3-2 on aggregate.

United legend Jaime Moreno opened the scoring for DC, but poor marking led to a late first half equalizer for Adolfo Bautista and Chivas, and United goalkeeper Troy Perkins' mistake lead to the winner from a Gonzalo Pineda strike early in the second, DC's website reported.

Fred officially left the A-League champions last week after a lucrative offer from the MLS club had been tabled.
