Paul correctly predicted the results of all matches played by Germany including the 1-0 defeat to Spain in the semi-finals. He predicted the Germany's victory over England, Argentina and Serbia.

Aquarium authorities normally put mussels into two glass boxes, with one box having Germany's flag and other with opponent's flag. The two boxes are then lowered into his tank and he is left to choose one box to open to retrieve the mussel. The box Paul opens first is regarded as his pick. Paul's picks have become news across the world. German news channels broadcast Paul's prediction live. He is one among the top 10 trends on Twitter.

The fans are happy and the prediction comes as a boost to the Spain ahead of the final against Holland at Soccer City Stadium, Johannesburg on Sunday.
