Roberto Pereyra watched on as an Argentina side missing Lionel Messi and Sergio Aguero drew 0-0 with Chile in a fractious friendly at the Los Angeles Coliseum which produced 10 yellow cards.

On paper it was a repeat of July's Copa America third-place play-off, a game in which Chile's Gary Medel and Messi were both sent off, but with the main stars missing it was much less of a spectacle at the Los Angeles Coliseum.

Manchester City striker Aguero was rested while Messi is serving a three-month international ban for his derogatory remarks about officials at the Copa America.

Argentina boss Lionel Scaloni made six substituions during the game but chose not to give the Watford midfielder a chance to add to his 17 caps as he remained on the bench throughout the 90 minutes.

Chile's best chance fell to Eduardo Vargas early in the second half but he fired over, while Argentina debutant Lucas Martinez almost won it but saw his header rebound off the crossbar five minutes from time.

Meanwhile, Craig Cathcart was given the night off as an experiemental Northern Ireland side beat Luxemboug 1-0 in a friendly.

Michael O'Neill's men face Germany in a Euro 2020 qualifier on Monday and the Hornets defender was one of several key players the Northern Ireland boss chose not to risk.

Domingos Quina played the first half as Portugal Under-21s started their European Championship qualifying campaign with a 4-0 victory over Gibraltar, helping to set up the opening goal.

The Watford midfielder played the pass forward that saw Francisco Trincao strike a long-range effort to make the breakthrough after eight minutes.

With his side 2-0 ahead at the break in a one-sided contest, coach Rui Jorge decided to make four changes at the start of the second half, including replacing the 19-year-old.
