Sigmund, the nicest guy imaginable off the field, is a trooper on it and Smeltz will be well aware there will be no favours and probably not the space which has seen him net a plethora of goals in recent weeks which has coincided with the return of Liam Miller to the Glory midfield.
Smeltz countered Sigmund's assertions by saying the Phoenix were a one-man band with Paul Ifill the only player capable of getting Ricki Herbert's team across the line.
If Sigmund is to be the player charged with containing the rampant Smeltz, Manny Muscat, who will play outside him at right back, has his own motivation to keep the season going.
Muscat's father Frank celebrates his 60th birthday today and there would be no greater present for Muscat to hand his father than a win tonight and the chance for his father and mother - his greatest fans - to be at next week's major semifinal against either Central Coast Mariners or Brisbane Roar.
"It would be really special for both of us if I could give him a win for a present," said Muscat. "He's followed me all over since I started playing and he and mum come to the games whenever possible."
Both teams will be at full strength for the game which precedes tomorrow's second leg of the major semifinal between the Mariners and the Roar with the winner progressing to the grand final and the loser to face either the Phoenix or the Glory.
