He struggled to establish himself in the Chelsea first team and with the likes of John Terry, William Gallas and Ricardo Carvalho ahead of him in the pecking order at Stamford Bridge, he joined Middlesbrough in August 2006 for a fee of £6 million.

He spent three years at the Riverside and after the club was relegated in 2009, Huth signed for Stoke City for a then-club record fee of £5 million.

He was unable to force his way back into the team and he joined Leicester on loan in February 2015, helping them avoid relegation from the top flight.

Huth made his debut for Chelsea at the age of 17 in the last game of the 2001–02 season, coming on as a substitute at half-time for Jesper Grønkjær in a 1–3 home defeat against Aston Villa.

[13] At the end of the 2005–06 season, Huth stated that he was unhappy with his lack of first team chances, prompting Middlesbrough, Wigan Athletic and Everton to submit bids for his services.

[26] He made his return as a substitute in an FA Cup tie against Manchester United on 19 March 2007,[27] but shortly afterwards he again picked up an injury in a 3–1 defeat against Aston Villa.

[28] Huth underwent ankle surgery in the summer of 2007 in order to fix his problem;[29] he consulted a specialist after failing to recover.

[37] He returned to the side in December time and by February the team had been enduring a tough season and were in deep relegation trouble.

[38] Boro failed to improve and they suffered relegation to the Championship, losing 2–1 to West Ham United on the final day of the season.

[43] On 17 October, Huth punched Matthew Upson in the face during a match against West Ham, though he received no card from the referee.

[62][63] After a series of poor defensive performances by Stoke, however, Huth returned to his centre-back pairing with Ryan Shawcross, going on to score his first goal of the season against Everton.

[76][77] He played 39 times for Stoke in 2012–13 as the side finished in 13th position; at the end of campaign, manager Tony Pulis was replaced by Mark Hughes.

[88] Huth's arrival at Leicester saw the Foxes embark on a run of seven victories in their final nine fixtures, which saw them retain their Premier League status.

[90] Huth completed a permanent transfer to Leicester on 24 June 2015, signing a three-year contract for an undisclosed fee, reported to be £3 million.

[93] On 6 February, he scored twice in a 3–1 win at title rivals Manchester City, putting Leicester six points clear at the top of the table.

[95] He missed only three league games as a result of a retrospective three-match suspension by The FA for pulling Marouane Fellaini's hair during a 1–1 draw at Manchester United on 1 May 2016.

[97] Huth remarked in an interview in November that he thought referees were getting penalty decisions wrong "a lot of the time" and felt he was being judged on "reputation".

[98] He admitted in a post-match interview on 2 January 2017 that his side were lucky not to concede a penalty when he brought down Adama Traoré in a goalless draw at Middlesbrough, a view not shared by Pat Nevin, watching the game for BBC Radio 5 live.

[99] Huth missed the entire 2017–18 season due to ankle and foot injuries, eventually opting to leave the club in June 2018.

Huth was called up on 16 August 2004 in the Germany national team, when he was nominated for the friendly match at the Ernst Happel Stadium in Vienna against Austria.

He was recalled to the Germany national team, last done for the 2006 World Cup, for a friendly against Switzerland on 20 March 2008 owing to his impressive recent club form.

[107] Growing up in Berlin, Huth decided to support Werder Bremen, as local Hertha BSC were rarely on TV.

[108] In January 2015, the FA began an investigation into Huth after he took part in a game on Twitter in which users guessed the gender of people in sexually explicit photos.
