Friedel made amends for his error as he tipped over a chip from Deco and then denied Drogba at point-blank range, then seven minutes into the second half Dunne's fellow center-back James Collins put Villa ahead from another Young corner as he was left unmarked at the far post.
Namibia finished on a high note when center Bradley Langenhoven intercepted a pass from Yannick Jauzion and ran it back from inside his half to touch down.
