Cameroon whizkid Jean Marie Dongou struck twice for Barcelona in their 7-0 rout of Valerenga in Norway. First half goals from Alexis, Cristian Tello, Lionel Messi and Jonathan Dos Santos and from Dongou (2) and Joan Román in the second brought FCB their first win of the preseason, and a major boost to their confidence after the 2-0 reverse at Bayern Munich on Wednesday.

New Barça manager, Tata Martino, was watching from the stands in the Ullevaal Stadium.

"It feels good to score two goals with the first team, it's special," said Dongou.

"It was a great experience to get playing time with the senior side."
