MLS All-Star conflict with CONCACAF Champions League sends the wrong international message 1 Feb 2011 Major League Soccer continually talks about the importance of having its teams succeed in international competition but, once again, the league has placed its All-Star game in direct conflict with the CONCACAF Champions League. MLS announced that it will host its annual All-Star Game July 27 at Red Bull Arena. But, as has been the case with the last two All-Star events, it clashes with the preliminary round of the CONCACAF Champions League. CONCACAF has already slated July 26-28 as the window for the first legs of the opening round.
