ФК Юнайтед Сикким

Foundation

The professional club was founded in 2011, by Sikkim Football Association (SFA) and Baichung Bhutia, already competing in the Sikkim Gold Cup and other all-India tournaments for the early years of their existence. On 22 March 2011, the club was launched as a professional, which would be co-owned by Dubai-based Fidelis World, former India football captain Bhaichung Bhutia and Indian singer Shankar Mahadevan. The club revealed that they would compete in the 2011 I-League 2nd Division, in the quest for promotion to the I-League within the next three years.

2011–2012: 2nd Division seasons

The club started their quest for the I-League on 27 February 2011, when they signed Liberian international Johnny Menyongar from NSC Minnesota Stars of the North American Soccer League in the United States. The club played their first match of the 2011 I-League 2nd Division against Langsning F.C. on 31 March 2012, in which they drew 2–2. United Sikkim won their first match of the season five days later, on 5 April 2011 against North Imphal Sporting Association at the Indira Gandhi Athletic Stadium in Assam, by a score of 2–0. The club finished in first place in group A of the first round of the I-League 2nd Division and thus qualified for the 2011 I-League 2nd Division final round, in which they only needed to finish in the top two for promotion. The club began Final round with three consecutive draws against Sporting Clube de Goa, Royal Wahingdoh and Shillong Lajong, before winning two matches in a row against Mohammedan and Southern Samity. Next, a draw to Ar-Hima and a loss to Vasco officially knocked United Sikkim out of contention for promotion and forced them to settle on fifth place for the season.

The season including the 2012 I-League 2nd Division did not start well for United Sikkim. On 11 June 2011, it was announced that Johnny Menyongar would leave the club to join I-League team Shillong Lajong, as well as Indian internationals Renedy Singh and NS Manju few months later. However, after firing coach Stanley Rozario, United Sikkim signed Belgian Philippe De Ridder as coach of the team. The club re-signed Nigerian players Daniel Bedemi and Quinton Jacobs for the season. They then began charge for the I-League for the second season in a row with a 3–2 victory over Bhawanipore F.C. at the Satindra Mohan Dev Stadium in Assam on 2 February 2012. The club went on to win three more matches during the first round of the I-League 2nd Division against Eagles, Southern Samity and Ar-Hima in order to qualify for the final round. They won promotion on the last day of the season on 17 April 2012 at the Paljor Stadium in front of 30,000 fans, as United Sikkim drew Mohammedan 1–1, with Daniel Bedemi scoring.

On 13 November 2012, Bhutia was named the interim manager to replace Belgian Philippe De Ridder, after the club's heavy 1–10 defeat in an I-League match against Prayag United on 10 November 2012 at the Salt Lake Stadium.

2012–2013: I-League

Later it was initially reported that United Sikkim had started talks with Australian manager Nathan Hall about a possible head coaching role at the club. On 10 December 2012, it was officially confirmed by United Sikkim that Hall had joined the club as its new head coach, replacing interim player-coach Bhaichung Bhutia. His first game as head coach of the club in the league came on 15 December against Mumbai at the Balewadi Sports Complex in which United Sikkim lost 0–1. Hall then managed to earn his first point as head coach in his next match against ONGC on 29 December in which his side drew 1–1 at the Ambedkar Stadium with Nadong Bhutia scoring the first goal for United Sikkim under Hall.

United Sikkim did not win a single game under Hall until 27 March 2013 in which his side managed a 5–0 victory over forced-relegated side Air India at the Paljor Stadium. This would turn out to be United Sikkim's last win and points for the rest of the season as the side lost its last four matches after this one and were thus relegated to the I-League 2nd Division.

2013: Travel to Bhutan

In March 2013, United Sikkim went to Bhutan for training. In their first foreign tour, they played three friendly matches against local sides Drukpol, Yeedzin and Zimdra at the Changlimithang Stadium in Thimpu.

From July to August, they went to Bhutan again and participated in 2013 King's Cup, in which they moved to the knockout stages. In the first semi-final, United Sikkim lost 2–4 to Manang Marshyangdi of Nepal.

2014: I-League 2nd Division

They also participated in the 2014 I-League 2nd Division and moved to the final round of I-League Qualifiers, finishing on fourth position with seven points in eight matches.

2014–2018

On 18 December 2014, it was revealed by owner Bhaichung Bhutia that United Sikkim had decided to leave the competition as future of the I-League was dim due to the formation of ISL, and thus team would only participate in the local league. In 2016, they took part in Bordoloi Trophy in Assam.

In February 2018, United Sikkim went to Nepal and participated in the 16th edition of Aaha! Rara Gold Cup, in which they failed to reach the knock-out stages.

2020–present

The All India Football Federation (AIFF) was all set to invite bids for vacant spot in the I-League and Gangtok-based United Sikkim Football Club were one of the front-runners to submit it for 2020–21 season. However, the bid was won by Sudeva Moonlight (currently Sudeva Delhi) from Delhi.

United Sikkim was the club that brought the I-League to the state where league matches were played at Paljor Stadium, and now we want to bring Indian Super League (ISL) to Sikkim. We will continue to give a platform to footballers from Sikkim and the region and in the process, contribute to the development of Indian football. The players will be scouted from different parts of the region
