Carson, Calif. In an interesting aside to Saturday's 2-1 victory by the L.A. Galaxy, as the game wound down, Real Salt Lake coach Jason Kreis was involved in a heated back-and-forth discussion with David Beckham.Apparently Beckham, known to be a bit of, for a nice term, a temperamental lad, was upset that Kreis had yelled at referee Kevin Stott, who issued six yellow cards.RSL had been hit with four cautions."Apparently [Beckham] thinks he's the only one who can yell at referees," Kreis said. "He wanted to continue [the discussion] after the game."Kreis would have none of it, calling Beckham disrespectful. Kreis said he never talks to players and, as a player, never talked to coaches.
