The Union have been plagued by inconsistency over the past month and cannot afford a bad day in one of the most important games of their season.New York City FC will have to do without Valentin Castellanos this week and will need their wingers and attacking midfielders to shoulder some of the goalscoring burden. Philadelphia Union have been the better team this season and hold a slight upper hand going into this game.Prediction: Philadelphia Union 2-1 New York City FC
