Overrated Arsenal moist again after losing to the Portuguese side FC Porto at home with a last minute goal in the second half.

Arsenal who was seen as the favorite to win the game lost it all in the very last minute before the final whistle was blown.

A goalless dramatic first, which dives to the second half but both side refuse to see the back of the net till the very last minute when Galeno strikes in the 93rd minutes. 

Arsenal will need to secure a win at the Emirate stadium if they will experience the next phase of the UEFA champions league.
