A Sony Norde brace helped Mumbai City upset first-placed Atletico de Kolkata in their Indian Super League regular season finale on Friday.

Norde's winner in second-half stoppage time capped a wild finish that saw three goals in the final 12 minutes of action.

The Haitian attacking midfielder opened the scoring in the 26th minute, only to see Atletico's Iain Hume equalise just before the half.

Sunil Chhetri looked to have given Mumbai the points with just eight minutes remaining in the contest. However Arata Izumi drew the hosts level in the 90th minute before Norde settled the score four minutes later.

Out of the playoff picture, the win sends Mumbai into the offseason on a high, while Atletico are left to prepare for their postseason opponent.
