The Philippines showed everyone that they are not competing in the AFF Suzuki Cup 2010 just for fun with a 2-0 win over Vietnam at Hanoi 's My Dinh Stadium on Dec.5.

The visitors created the biggest upset of the tournament so far with a strong defensive display that left defending champions Vietnam searching for answers in their second group B match.

It was the first time the Philippines had ever beaten Vietnam in an international tournament.

Chris Greatwich opened the scoring for the Philippines in the 38th minute and Philip Younghusband added a second in the 78th minute, both from counter-attacks resulting from mistakes by the hosts who left themselves thin at the back as they went in search of a goal.

The Philippines now top group B with one win and one draw, and know that they only need a draw in their next game against Myanmar to book a place in the semi-finals.

Vietnam takes on Singapore on Dec. 8 and need to win in order to be guaranteed of a semi-final spot. A draw would only be good enough if Myanmar defeat the Philippines , which many people think is highly unlikely.

In the early match on Dec. 5, Singapore came from behind to beat Myanmar 2-1 to rank second in the group while Vietnam dropped to third after two matches./.
