In international football, the club has participated in seven Asian competitions to date, most notably reaching the AFC Cup inter-zone play-off final in 2019.

[2] Once the club established its foothold, Hanoi T&T began to rapidly emerge as a strong contender and experienced success in its debut season in the top league.

The 2014 and 2015 seasons marked the rise of Becamex Bình Dương, and it was also a transitional period for Hanoi T&T as a new generation of players, including Duy Manh, Van Thanh, and Minh Long, were promoted to the first team.

In the 2014 AFC Cup, Hanoi T&T finished first in Group F, defeated Nay Pyi Taw 5–0 in the Round of 16, but were eliminated in the quarterfinals by Erbil of Iraq, losing 3–0 on aggregate.

In the penultimate round, needing a win to keep their championship hopes alive, Hanoi T&T secured all 3 points with a 1–0 victory over Than Quang Ninh, thanks to a goal from Nguyen Van Quyet.

A 2–0 victory over FLC Thanh Hoa, featuring a double from Gonzalo, allowed Hanoi T&T to win the V-League championship for the third time, finishing just above Hai Phong on goal difference.

In the 2018 season, the success of the Vietnam U23 team in the 2018 AFC U-23 Championship, where Hanoi players played a crucial role, significantly boosted interest in the club.

However, the season ended on a disappointing note when the team missed the opportunity to reach the 2018 Vietnamese Cup final after a goalless draw against Becamex Binh Duong at Gò Đậu Stadium.

In 2019, Hanoi started the season with a victory in the AFC Champions League round 1 play-off, winning 1–0 against Thai club Bangkok United.

However, in the second play-off match, Hanoi suffered a 2–4 defeat to Chinese team Shandong Luneng despite taking the lead in the first half and putting in a strong performance.

Domestically, the season began with a 2–0 victory over Becamex Binh Duong in the Super Cup, followed by a remarkable 5–0 win against Than Quang Ninh.

The team faced a tougher title race than in the previous season, competing in three different competitions—V.League 1, the Vietnamese Cup, and the AFC Cup—and contending with the rising side Ho Chi Minh City.

Hanoi FC dropped points in stoppage time against underdogs like Hoang Anh Gia Lai, Sanna Khanh Hoa BVN, and direct competitors Ho Chi Minh City.

In the 2019 AFC Cup, Hanoi topped Group F and progressed through the knockout stage, overcoming Ceres Negros, Becamex Binh Duong, and Altyn Asyr to reach the inter-zone final.

Despite playing away and in adverse weather conditions due to a storm, Hanoi won the 2019 Vietnamese Cup, adding the only major trophy previously missing from their collection.

In the 2023 season, under Montenegro head coach Bozidar Bandovic, Hanoi started by winning the 2023 Vietnamese Super Cup after defeating Haiphong in the final.

However, in their fourth group match, Hanoi FC bounced back with a 2–1 victory over Wuhan Three Towns at home, with both goals scored by Phạm Tuấn Hải.

In their final match, the club achieved a 2–1 victory over Urawa Red Diamonds, eliminating the champions from defending their title and handing them their first loss against an ASEAN side in 16 years.

During a visit to France by Nguyễn Phú Trọng, the General Secretary of the Communist Party of Vietnam, in 2018, he and French President Emmanuel Macron signed several cooperation agreements, including one for the rebuilding and renovation of the stadium.

[5] The club has a relatively small, if not low, number of supporters despite its prestigious achievements, partly due to past corruption in the V.League, which led many people to lose interest in attending matches.

After facing early difficulties and conflicts with older fans, Contras Hanoi grew to over 2,000 followers on Facebook by 2018 and has continued to expand, working to gain official recognition with the club's support.

[10] In the 2017 season, Hải Phòng was disciplined for causing disturbances in their match against Hanoi during the 6th round of the V.League, resulting in a ban on fans attending away games.

Mr. Tran Anh Tu, Chairman of the Board and General Director of VPF, remarked that the match between Hanoi and Hải Phòng had "the most firecrackers ever" he had witnessed.

Vu Xuan Thanh, Head of the VFF Disciplinary Committee, noted that Hải Phòng fans had brought boxes of flares into the stadium.

[11] Công An Hà Nội's rapid rise challenged Hanoi FC's dominant status in the league, leading to a new rivalry between the two teams.

[12] In the 21st century, Hoang Anh Gia Lai and Hanoi FC are widely regarded as the most supported clubs in Vietnam, and their confrontations are dubbed the "Vietnamese Super Derby."

However, the intense rivalry gained significant attention starting in 2018, when U23 Vietnam, featuring many players from both clubs, finished as runners-up in the AFC U-23 Championship.

Since then, matches between Hoang Anh Gia Lai and Hanoi FC have attracted substantial media coverage, as the competition extends beyond the field to include differing football philosophies and management approaches,[13] particularly between their owners Đỗ Quang Hiển and Đoàn Nguyên Đức.

Nam Định fans began to follow in Hải Phòng's footsteps by setting off flares at Hàng Đẫy Stadium as an act of revenge against Hanoi FC.

Nguyễn Đức Chung, Chairman of the Hanoi People's Committee, directed the City Police to focus on investigating, clarifying, and strictly handling those responsible for the incident.
