Following their 2-0 win in Amsterdam and Hernandez's goal, United conceded twice at Old Trafford, setting up a dramatic finish, but they held on for a 3-2 aggregate victory to advance to the Round of 16. They will meet Athletic Bilbao, who advanced earlier on Thursday.
Hernandez's sixth-minute strike was set up brilliantly by a lightning fast counterattack by the Red Devils. Park Ji-Sung started it with an interception and Dimitar Berbatov provided the assist with a great ball over the top. Hernandez beat his defender with a great cut-back dribble before placing the ball past Kenneth Vermeer to extend his team's lead in the tie.
Aras Özbiliz scored on a bit of a scramble, taking advantage of some poor defending by United to score in the 37th minute. Things got dramatic in the 87th minute when Toby Alderweireld headed in a free kick by Özbiliz to make it 3-2 on aggregate, but Ajax would not create another good chance as United held on for the victory.
