The Mustangs, a Central Division team in the Major Arena Soccer League, played their home games at the Sears Centre in the Chicago suburb of Hoffman Estates, Illinois.
The Mustangs, PASL champions in 2013–14, struggled in the first year of the MASL but managed to amass an 11–9 record, good enough for 3rd place in the Central Division and a berth in the playoffs.
Playing a home-and-home series for the Division Semi-Finals, Chicago beat Milwaukee at the Sears Centre but lost the second game and the tie-breaking mini-game (in overtime) on the road.
The Mustangs were successful in their inaugural season in the Professional Arena Soccer League, finishing 11–5, but failed to qualify for the postseason in the competitive Central Division.
[11] With the league expansion and reorganization, the Mustangs move from the Eastern back to the Central division where their rivals for 2014–15 are the Milwaukee Wave, St. Louis Ambush, Tulsa Revolution, Wichita B-52s, and Kansas City-based Missouri Comets.
