HOUSTON, United States (AFP) β Cristiano Ronaldo became the first player to score in six World Cup campaigns and silenced his critics as the Portugal captain struck twice in a 5-0 annihilation of Uzbekistan on Tuesday. The big win in Houston put Portugal on the brink of the knockout rounds and was a resounding response to the 41-year-old's doubters. Ronaldo's goal after six minutes made history -- trumping even Lionel Messi -- by scoring at six World Cups stretching back to 2006.
