COVILHA (Portugal) (AFP) Portugal claimed a deserved 3-1 friendly win over Cameroon on Tuesday, a victory that was given a helping hand by the first half sending-off of Inter Milan striker Samuel Etoo. Portugal dominated the early stages and opened the scoring just after the half hour mark through FC Portos Raul Meireles. Etoo protested the goal to the referee and, having already been booked for a foul on Portugal defender Duda, the Cameroon star was shown a second yellow and then a red card in the 33rd minute. Portugal took advantage of their numerical superiority and the on-form Meireles grabbed his second of the game in the 46th minute. Etoo was making his first appearance for Cameroon since helping his Italian club to an historic treble of the Serie A title, Italian Cup and Champions League. However even in his absence the Indomitable Lions, who will play Denmark, Japan and the Netherlands in Group E of the World Cup, fought back valiantly and reduced arrears in the 69th minute when Webo rose to meet a superb cross into the area and fired a bullet header Cameroon hustled and bustled in a bid to grab an equaliser but despite Portugal midfielder Pedro Mendes leaving the field with an injury in the 72nd minute the Africans were kept in check. Real Madrid striker Cristiano Ronaldo has struggled to make an impact for his national side in recent months and that streak continued, with Manchester Uniteds Nani providing the hosts third goal nine minutes from time. Portugal fly out to South Africa later this week and open their tournament against Ivory Coast on June 15, with further Group G matches against Brazil and North Korea.
