SOCHI, Russia (Reuters) - Mexico coach Juan Carlos Osorio has apologised after television cameras caught him using an expletive during Wednesday's ill-tempered Confederations Cup match against New Zealand.

Osorio said he was incensed during the first half of the game when Mexico defender Carlos Salcedo was left injured after a clash with rival forward Chris Wood in the New Zealand area and their opponents failed to kick the ball out of play.

New Zealand played on, went down the other end and nearly scored, with the Mexicans urging their opponents to stop the game.

"I want to apologise to all the television viewers, I obviously went over the top when I got involved with their assistant coach," he told Mexican media after his side's 2-1 win.

"The situation in which Carlos Salcedo was left on the ground gave them a goalscoring chance," added the Colombian. "Our players and myself were shouting at them and the New Zealand coach to stop the match."
