United SC was originally established in 1927 as Eveready Association. In 2006, it was renamed as United Sports Club to attract title sponsor and the football division owned by United Sport Football Team Private Ltd. With the inflow of sponsorship, the club clinched promotion to the first division of the I-League in 2007.
For the 2010-11 I-League season United SC played at the Salt Lake Stadium in Kolkata. On Indian Transfer deadline day United SC made the biggest headline news by signing India national football team striker Sunil Chhetri till the end of the season. In June 2011 after the I-League season ended old sponsors Chirag chose to cut ties with United SC and thus Chirag United SC became Prayag United Sports Club. Even though the team has lost a lot in terms of sponsorship money the club is still able to sign and retain their current players. On August 3, 2011 it was announced that United Sports Club had signed a sponsorship deal with Prayag Group and on August 7, 2011 United Sports Club officially changed their name to Prayag United S.C.
The association, however was cancelled in the summer of the 2013, when the company found itself involved in the chit-fund scam. The name was again changed to United Sports Club.
Struggle for Sponsorship and performance in I-League
United SC are yet to bag a title sponsor. Their capture of Eric Brown from disbanded ONGC side has been their best activity in the summer.
The club crest is designed in the shape of a blue and white circle. The logo includes the words 'United Sports Club' in the blue strip of the crest. This is to show United Sports Club as the main name of the club. Inside the crest is a peacock on top of a football.
While the crest is Blue and White, the official colours of United SC are purple and yellow. While still sponsored and owned by Chirag Computers, United Sports Club's official colours were purple and white. The home kit for United SC includes a purple and yellow jersey with purple shorts and white socks while the away kit is all white with red socks.
United Sports Club currently plays at the 10,000 seater Kalyani Stadium in Kalyani. Though the officials initially said that they would move to Siliguri but now they have decided to stay in Kalyani for the 2013–14 season and plan to continue there.
