Andreas Hannes Ling Fung Nägelein (traditional Chinese: 聶凌峰; simplified Chinese: 聂凌峰/安迪·内格雷恩; Jyutping: nip⁴ ling⁶ fung¹; born 5 October 1981), commonly known as Andy Nägelein, is a Hong Kong footballer of partial German descent. Nägelein began his career in Germany and he left to Cyprus and China in short term. He is currently a free agent. His usual position is as a defensive midfielder primarily, but he can also be utilized as a centre back or a full back.
Nägelein was born on 5 October 1981 in Hong Kong, his father, a German working in Hong Kong, and his mother, a Hong Kong  He has a sister, who was also born in Hong Kong. When he was a year old, his family went back to Nuremberg, Germany.
At the age of five, Nägelein started playing football for a local club and he scored 170 goals in the league, so Nägelein switched to 1. FC Nuremberg and stayed for nine years. He played as a striker as a young player, but he currently plays as a midfielder. This is because his coach told him that "offense can win a game, but defense wins championship". After the Nuremberg era, he switched to different German clubs and he started his professional career in age 19.
Nägelein started his senior career with SC 04 Schwabach in the Oberliga Bayern. He moved to 1. FC Schweinfurt 05 in 2003. After Schweinfurt 05 released him in 2004, Nägelein joined 1. SC Feucht. However, Feucht was relegated at the end of the 2004–05 season, so he joined a new Regionalliga Nord club Kickers Emden. After good performances at Kickers Emden, he moved to SV Wacker Burghausen in the 2. Bundesliga. After half a year, he returned to Kickers Emden. He was one of main players at the club in following two and half seasons. After the 2008–09 season Emden voluntary withdrew from the league because of license restrictions, and Nägelein left the club.
In 2009, Nägelein signed for the Cypriot club APEP Pitsilia, it was his first time to play in a top division league. Nägelein attracted the interest of Asian clubs because he was born in Hong Kong. This is the reason to explain why Nägelein left for China before 2010 Chinese Super League started.
He was reportedly in talks with a number of Chinese clubs, including Shandong Luneng. On 12 February 2010, Shenzhen Ruby announced they had reached an agreement signing Nägelein. Nägelein chose this club since Shenzhen is situated just north of Hong Kong. Nägelein was in the regular lineup of Shenzhen and created the best opening season since the club was founded. In a league match against Changchun Yatai on 18 April 2010, over one-third of fouls by Yatai players attacked him due to his enormous playing area.
Nägelein's injury in May 2010 made Shenzhen in low tide. He came back to the field after the 2010 FIFA World Cup but Shenzhen Ruby lost to Tianjin Teda 2–1. Nägelein had a rest after this match due to his injury. He introduced his friend to South China and chairman of South China Steven Lo said he will contract two drained Hong Kong footballers simultaneously, so Hong Kong media thought one of two is Nägelein. Nevertheless, Lo said he never talked about this with Nägelein.
During the training in Shandong Sports Center on 17 September 2010, Nägelein quarreled with Vyacheslav Hleb by English profanity. After that, the oldest foreign player Aleksandar Živković came out to mediate. Shenzhen Ruby lost 3–2 to Shandong Luneng on 18 September 2010, and this was the fourth straight loss games of Shenzhen Ruby.
He finished his first season in China with Shenzhen Ruby as 13th place in the league. After the season, Nägelein was handed shirt number 7, and was chosen as the regular start-up player of the team by new coach Philippe Troussier.
Troussier tried to let him play as centre back in the new season. Lamentably, Shenzhen would not have a good start in the 2011 Chinese Super League, suffering five straight losses, and the worst start ever since the club was founded. On 8 May 2011, Nägelein failed passing the ball in the 68th minute of the match against Guangzhou Evergrande, and caused Shenzhen to lose by a goal. After that, Nägelein's teammate Huang Fengtao criticised him for his mistakes on the Sina Blog. After that, Troussier replaced Nägelein in midfield and Shenzhen got their first point after the match against Dalian Shide on 15 May 2011.
Nägelein assisted Chris Killen to score in the 57th minute of the league match against Changchun Yatai, which impressed others but he became mainly used as a substitute later in the season, because Nägelein has been injured and Shenzhen had contracted Ronald Rivero in the summer. Nägelein went back to the field on 2 November 2011, but Shenzhen had regulated the previous week. He was released by Shenzhen at the end of 2011 league season.
Nägelein was signed by Hong Kong First Division League side Hong Kong Rangers in August 2012. However, Nägelein tragically broke his leg after a terrible tackle by Chan Pak Hang in a league match against Sun Pegasus on 8 September 2012. He had three-month leave for treatments and recovering training in Nuremberg, Germany. The contract with Rangers ended in the end of January and Nägelein has become free agent player again.
On 6 July 2013, Nägelein signed a contract with China League One side Guizhou Zhicheng., from where he transferred to China League One side Hunan Billows on 27 February 2014. In 2015 he went back to Hong Kong, joining Eastern AA this time, with whom he won the Senior Challenge Shield and the Premier League in 2016.
In principle, Nägelein can represent either the German or Hong Kong national teams because he has both German citizenship and right of abode in Hong Kong. However, Nägelein controversially failed in his application for a Hong Kong passport due to his German citizenship, even he has the right by Hong Kong Basic Law since he was born in Hong Kong to a Hong Kong Chinese mother.
After Nägelein returned to the Far East, Hong Kong coach Tsang Wai Chung told media he will call Nägelein for the team but Tsang did not select Nägelein for the training session before the 2010–11 season in Hong Kong. Tsang explained that some players would be called up during the season, but Nägelein was not chosen by Tsang for any training session in the season.
Under FIFA eligibility rules, Nägelein could also play for the Chinese national team after a two-year Chinese Super League career for his Hong Kong passport. Nägelein recommended himself via his agent to Chinese Football Association in 2010, but the association told him that China team would not select him for any match.
On 2 August 2013, the Hong Kong national team included Nägelein in the 29-man training squad for two international friendlies against Myanmar and Singapore in September 2013. On 3 October 2013, Nägelein did break into the 23-man final squad for 2015 AFC Asian Cup qualification match against United Arab Emirates. He made his international debut for Hong Kong against United Arab Emirates on 15 October 2013.

And his Chinese given name Ling Fung (Chinese: 凌峰) is the same with his grandfather's name. Nägelein met his girlfriend in Nuremberg since he studied at business college for a short time when he was 18 years old. He now lives in Hong Kong.
