Christian Pulisic scored twice as the United States beat Mexico 3-0 on Thursday to set up a CONCACAF Champions League final showdown with Canada after a stormy battle that saw both sides finish with nine men. 

Chelsea winger Pulisic opened the scoring in the 37th minute and then drove in a second a minute after the interval, slotting home a low cross from Tim Weah, who had been sent clear down the right by a fine long pass from Weston McKennie.
