This was young Gurmeet and Hyderabad's first ever major trophy.[7][8]
The following season, he missed the Durand Cup and opening seven games of the league due to an injury but became the first choice keeper upon his return due to Laxmikant Kattimani's knee injury which ruled the latter out for rest of the season.[9] He started his first game of the season in a 1-0 loss to Mohun Bagan.[10] In the league stage, he kept five cleansheets and conceded only nine goals in twelve games with Hyderabad finishing second in the league.
