Arturo Vidal brushed off a hotly disputed video review to give Chile a 2-0 win over Cameroon in the Confederations Cup on Sunday.
Vidal s 81st-minute header after a pass from substitute Alexis Sanchez gave the South American champion a Group B win which was anything but routine, before another goal was decided by video review.
The Chileans had thought they d taken the lead in first-half stoppage time when Eduardo Vargas slotted the ball past Fabrice Ondoa after a pass from Vidal.
Referee Damir Skomina awarded the goal and Chile s players started an elaborate goal celebration, but the decision was then sent for video review - the key piece of new technology being debuted by FIFA at the Confederations Cup.
Players milled about in confusion, some briefly appearing to think the referee had blown for half-time, and Chile s many traveling fans struggled to understand what was going on.
The review found Vargas offside by a matter of inches, enraging him and Vidal, who angrily petitioned Skomina when he blew for half time.
After Vidal put Chile ahead in the 80th, Vargas scored Chile s second - but only after another review.
Sanchez charged through the Chilean defense, but saw his shot saved by Ondoa, only for Vargas to score the rebound. The review found Sanchez hadn t been offside when he received the ball.
Chile dominated the game throughout, but couldn t finish several first-half chances.
Cameroon was under pressure immediately, when Eduardo Vargas first-minute shot cannoned off the post and rebounded back into goalkeeper Fabrice Ondoa, almost going in.
Ondoa had to palm away a Jose Fuenzalida shot two minutes later as Chile took firm control.
With Cameroon s defense playing narrow and ceding the flanks to Chile, Ondoa was also called upon to block a shot from Edson Puch, while Vargas blazed the ball over the bar in the 40th minute.
Cameroon s chances came thanks to occasional poor passing at the back from Chile, with Vincent Aboubakar forcing a save in the 11th from keeper Johnny Herrera, in for the injured Claudio Bravo.
The Cameroonians got the ball in the net once, but the whistle had already gone for a foul on Vidal by the time Michael Ngadeu Ngadjui headed the ball into the net at a 17th-minute free kick.
The controversial video review left Chile s confidence dented in the second half, as Cameroon started to push forward, though without creating clear-cut chances.
Cameroon captain Benjamin Moukandjo curled a free-kick narrowly off target in the 67th, while Chile had another chance when Mauricio Isla s header went narrowly wide at a corner.
