Dwyer, who has 52 goals since 2013, has just two goals in his career against RSL, both of which have come in losses. He scored in RSL's 3-1 win at Sporting KC in May and in Sandy last summer in a 2-1 loss at Rio Tinto Stadium.
"If you stop him one time, he's just going to keep going at you," RSL coach Jeff Cassar said. "You have to focus for the entire game. On top of that, he's lethal with his finishing. Typically, it doesn't take him a ton of chances to get his goals. His efficiency is really good, and on top of that, he can [score] several different ways.
