The young Brazilian, unmarked three metres out, clipped the ball into the net to bring the pro-Portuguese crowd of 40,078 to their feet at the SkyDome.

Both sides enjoyed good chances in a scoreless first half, Porto hitting the woodwork twice and Liverpool's Michael Owen twice missing the target with headers.

The Champions World Series features 11 friendly matches at eight venues across the United States and Canada, involving club sides from England, Italy, Scotland, Portugal, Germany and Turkey.

The next two matches are both on Saturday with Manchester United facing AC Milan in New Jersey and Celtic meeting AS Roma in Toronto.

Porto will also travel to New Jersey for their second game in the series against Galatasaray on Sunday.

Liverpool, who hammered Celtic 5-1 in Hartford last Monday, play their third and final match against AS Roma in New Jersey on Tuesday.
