Niels Frederiksen

Frederiksen returned to club management at the beginning of the 2019–20 season with Brøndby IF, when the club announced him as their new head coach on 1 June. However, Frederiksen would have to lead the Denmark under-21 team through the 2019 UEFA European Under-21 Championship before starting in his new position. In Brøndby, he had a mixed start and the club suffered a string of poor results in September. This saw him change the formation from a 4–3–3 to a 3–5–2 in early October, which resulted in a derby win over FC Copenhagen. Frederiksen's defense consisted of Hjörtur Hermannsson, Andreas Maxsø and Sigurd Rosted, which neutralised Copenhagen-strikers Nicklas Bendtner and Michael Santos. After winning the subsequent league match 3-0 over Frederiksen's former club, Lyngby, he stated that the 3-5-2 was a system suited for his team's abilities. In January 2020, sporting director Carsten V. Jensen sold key players Kamil Wilczek and Dominik Kaiser to Göztepe and Hannover 96, respectively, which brought forward Frederiksen's key strengths; the development of young players. The altering of the first-team meant that talents such as Morten Frendrup and Anis Ben Slimane began to play a larger role for the club in the spring of 2020.

On 10 August 2015, Frederiksen was dismissed by Esbjerg with the side placed last in the Danish Superliga table after four matches into the 2015–16 season, with chairman Søren Poulsen citing "lacking" domestic results as the reason behind the dismissal. Frederiksen was succeeded by Jonas Dal.

In August 2015, Frederiksen was named manager of the Denmark under-21 team, signing a two-year contract. In his first game in charge, they lost 1–2 to Germany in a friendly at Stadion Lohmühle in Lübeck, Schleswig-Holstein. Under Frederiksen, Denmark qualified for the UEFA European Under-21 Championship in 2017 and 2019, where they were knocked out in the group stages, finishing third and second, respectively.

Frederiksen is noted for his exceptional work with young talents, developing players such as Andreas Christensen, Andreas Bjelland, Yussuf Poulsen and Christian Nørgaard in Lyngby, and Martin Braithwaite at Esbjerg. He has furthermore shown flexibility in regards to formations, employing a 3–4–3 formation at Denmark U21, but also utilising a classic 4–4–2. In Brøndby, Frederiksen started out employing a 4–3–3, but has since adjusted this to a dynamic 3–5–2 with attacking wingbacks, Andreas Maxsø as the anchor in defense and Kamil Wilczek and Simon Hedlund as the main forwards. Frederiksen is a proponent of pressing, in what he has called a balanced press. This implies striking a balance between immediately attempting to win back possession high up the pitch, and falling back and regrouping in defence.

On 2 May 2013, Esbjerg fB announced that Frederiksen would succeed Jess Thorup as the club's head coach from the start of the 2013–14 Danish Superliga season. In his first season, he led Esbjerg to the round of 32 in the Europa League, where they lost 2–4 over two legs to Italian side Fiorentina. This came after advancing from the group stage in second place by beating Standard Liège (2–1 and 2–1) and Elfsborg (2–1 and 1–0), and losing two matches to group winners, Red Bull Salzburg (1–2 and 0–3). Esbjerg had qualified to the group stage after winning 5–3 on aggregate over French club Saint-Étienne. In the domestic league, his first season was also successful, ending in a fifth-placed finish which qualified the club for contention in the 2014–15 Europa League second round.

In the following season, Esbjerg knocked out Kazakh side Kairat Almaty 2–1 on aggregate in the second qualifying round, before facing Polish club Ruch Chorzów in the third round. In the first leg, Esbjerg drew 0–0 away. However in the second leg, a last-minute goal by Łukasz Surma for Ruch Chorzów to make it 2–2 to win on away goals, ended Esbjerg's hopes of advancing in the tournament. In the domestic league, Esbjerg had sold some profiles such as Jakob Ankersen, Eddi Gomes and Martin Pušić during the winter transfer window, and partly due to this the club struggled against relegation. In the last fixture of the season, Esbjerg avoided relegation after a 2–1 win over relegation rivals, FC Vestsjælland.

Frederiksen has cited his main influences inside football as José Mourinho "for his arrogance", Sir Alex Ferguson "for his long time success" and Jürgen Klopp, due to his development of young players and his tactics. Outside football, he has been inspired by Socrates and the 2011 film Moneyball starring Brad Pitt.

In early June 2011, Frederiksen became a full-time permanent employee in Lyngby. This happened after he signed a three-year contract extension, keeping him part of the club until June 2014. By 1 September 2011, Frederiksen was released from his employment obligations in the Danske Bank Group, and the following week he was appointed manager of Lyngby, where he was also put in charge of transfers. The same year, he received his UEFA Pro Licence.

During his tenure as coach and head of talent in Lyngby Boldklub, Frederiksen received his UEFA Pro Licence in 2011, and has since functioned as a coaching instructor in the Danish Football Union.

His favourite club is Borussia Dortmund, who he started supporting in 2011.

After reaching promotion to the Superliga, Frederiksen signed a one-year contract extension with Lyngby on 1 July 2010. While working as head coach at the highest level, he took leave as COO in Danske Bank and would only do consulting assignments. During the 2010–11 season, Lyngby was engaged in a relegation battle but managed to avoid this in the final fixture of the season, on 29 May 2011 in a 2–0 home win over OB. The club ended in eighth place in the league table.

Frederiksen began his career as a head coach at Lyngby Boldklub in 2009, after having spent almost two decades as a youth coach in B 1913, B.93 and Lyngby. He remained in the post as head coach, and later manager, for the club for nearly four years. He then coached Esbjerg, leading them to a fifth place in the domestic league as well as their best European result ever; the Europa League round of 32 where the club was knocked out by Fiorentina. He was relieved of his duties in 2015. He was later put in charge of the Denmark national under-21 team, before being appointed head coach of Brøndby in June 2019, replacing Alexander Zorniger.

Lyngby Boldklub's first team competed in the Danish 1st Division (second highest division) in 2009, where the club's objective was promotion to the Danish Superliga. After a poor start to the season, head coach Henrik Larsen was sacked on 23 March 2009. On the same day, Frederiksen was promoted from head of talent to head coach for the first team. Lyngby ended the 2008–09 season in sixth place, 21 and 19 points, respectively, behind Herfølge Boldklub and Silkeborg IF who reached promotion. He continued coaching the first team during the 2009–10 season while managing an HR unit within Danske Bank where he had also become chief operating officer. Frederiksen and Lyngby Boldklub reached promotion during that season, after reaching second place in the table, only behind AC Horsens and ahead of FC Fredericia in third place.

Frederiksen began coaching the Lyngby Boldklub under-17 and under-19 sides beginning 1 January 2006. During his first season, he led the under-19 team to a second place in the table in the national championship, while they reached third place in 2007. In February 2008, Frederiksen was promoted to the position of head of talent in Lyngby – the club's first since 2004 where Birger Jørgensen held the position. He also joined the board of the Lyngby Boldklub aktieselskab.

In 2005, Frederiksen was put in charge of the entire youth department of B.93, while he also worked as assistant coach to the first team which competed in the Danish 2nd Division (third highest division). In November 2005, he signed a contract as under-19 coach for Lyngby Boldklub, and he left B.93 in late 2005.

Frederiksen's arrived in B.93 from Østerbro, Copenhagen in 1997, where he was put in charge of some youth divisions. Between 2000 and 2002, he was appointed coach of the under-16 team and followed the players as coach when these reached the under-18 team in 2003–04.
