In a dramatic finale befitting one of football's most storied rivalries, Mohun Bagan Super Giant clinched their 21st IFA Shield title by defeating East Bengal FC 5-4 on penalties after a 1-1 draw at the Vivekananda Yuba Bharati Krirangan on Saturday. The victory marked Mohun Bagan Super Giant's first IFA Shield triumph since 2003, ending a 22 year wait that had seen them reach five finals without success.

Mohun Bagan Super Giant secured their place in the IFA Shield final with a composed 2-0 victory over United Sports Club at the Kishore Bharati Krirangan in Kolkata on October 15, 2025. Goals from Dimitrios Petratos and an own goal from United SC ensured the Mariners topped Group B and set up a highly anticipated Kolkata Derby final against arch rivals East Bengal at the Salt Lake Stadium.​
