In the year 2008, having had a series of brilliant displays in goal, Kolkata giants East Bengal FC approached the youngster and he finally signed for the team.
The following year, hearing of the keepers availability, Air India FC wasted no time in signing Sharma (on loan), making it his second-stint with the team.
Regaining his starting place in the I-League, Air India performed well and Sharma was said to have single-handed rescued the team on numerous occasions.
The green outfit were said to have the best keeper combination in the league with Karanjit Singh and Arnab Das Sharma in the same team.
After having a disastrous year in Goa, sharma had offers from a few I-League and a few Kolkata-based clubs but he opted to join I-League 2nd Division outfit United Sikkim FC, the team owned by iconic footballer Baichung Bhutia and sponsored by Bollywood playback singer Shankar Mahadevan and Dubai-based company Fidelis World.
