NATAL, Brazil, June 13 (Reuters) - Mexico and Cameroon were goalless at halftime in their World Cup opener on Friday after two Giovani Dos Santos efforts were controversially disallowed for offside on a rain-soaked pitch.
The Mexicans, cheered on by thousands of fans, dominated possession in the Group A match and created a number of chances on the slick pitch as they attacked down the wings.
Dos Santos twice had the ball in the net, the first a volley and the second a header off a corner kick. Samuel Eto'o came close for Cameroon, with a shot that just went wide. (Reporting by Michael Kahn, Editing by Nigel Hunt)
