Montreal came out on top in arguably the game of the season so far which was a thrilling 4-3 affair against FC Cincinnati on May 29.
After going behind to Junior Moreno's opener, Wilfried Nancy's men raced to a 3-1 lead thanks to goals from Joel Waterman, Romell Quioto and Mathieu Choiniere before Quioto added a second just shy of the hour mark to render strikes from Alvaro Barreal and the aforementioned Moreno inconsequential.
