The club is owned by Vita Dani, Bollywood actor Abhishek Bachchan and Indian cricketer MS Dhoni.

[4] The team's name Chennaiyin FC means Chennai's football club in Tamil where the 'yin' suffix is similar to a possessive 's' in English.

[5] The club's primary colour is blue ever since its inception and its logo is the Dhrishti Bommai, a representation of chasing away negativity and preserving positivity in the Tamil culture.

[7] However, on 11 April 2014 it was reported that Chennai's main bidder, a consortium led by Sunil Gavaskar would drop out due to commitments with the Board of Control for Cricket in India.

[8] In August 2014, with two months before the 2014 ISL season, the Bangalore owners Sun Group dropped out due to disputes with the organizers.

[10] On 14 August 2014, it was reported that ISL officials were inspecting the Jawaharlal Nehru Stadium in Chennai for the proposed team.

After a dismal season, it was announced on 6 March that Marco Materazzi and Chennaiyin parted ways on mutual consent.

On 3 July 2017, the club announced the appointment of former Aston Villa Manager John Gregory as the head coach for the 2017–18 season.

[23] The blues then travelled to Sree Kanteerava Stadium, where they beat Bengaluru FC 2–1 in a tightly contested match.

On John Gregory's 65th birthday the club announced that the coach's contract was renewed which will expire soon after the 2019–20 Indian Super League season.

After losing the AFC Cup the club then made some shocking decisions by releasing their captain, Mailson Alves and Raphael Augusto as a preparation for the 2019–20 Indian Super League season.

They then signed Nerijus Valskis, Lucian Goian, Dragoș Firțulescu, André Schembri, Masih Saighani and Rafael Crivellaro to strengthen their squad.

On 30 November 2019 John Gregory resigned from his post as head coach even though owner Mrs. Vita Dani tried in vain to get him to stay.

[28] Under his guidance Chennaiyin faced 1–1 draw against Jamshedpur, won 3–1 against Kerala Blasters and lost a dramatic game 4–3 to Goa in the initial days of Coyle.

[35][36] Chennaiyin were beaten 3–1 by ATK with the game played behind closed doors, due to the rise of the COVID-19 pandemic in India.

[40] Chennaiyin FC play their home matches at the Jawaharlal Nehru Stadium in Chennai nicknamed the Marina Arena.

The stadium is located at Sydenhams Road, Park Town behind the Chennai Central suburban Railway station and Ripon Building.

The stadium is named after Jawaharlal Nehru, India's first Prime Minister and earlier hosted cricket Test Matches between 1956 and 1965.

Indian captain Sunil Chhetri himself has acknowledged this fact, as he's usually been on the receiving end when he travels to the Marina Arena in BFC colours.
