Sigi Schmid admits he is not surprised by the fluid attacking partnership formed by two of his Seattle Sounders stars.
"Nothing surprises me with those two guys," Schmid told reporters after the game.
"They're just like that. I see it at practice all the time. They're able to conjure up magical stuff.
"They're unique and special and we're happy to have them on our team."
Martins netted twice and Dempsey once to take their respective season tallies to six and five from eight matches. They have also combined for six assists.
