West London club Chelsea signed Robert Huth from the youth team at German club Union Berlin in 2001 while Italian tactician Claudio Ranieri was the Blues boss. Huth began his Chelsea career in the youth team before he was promoted to the first team. In the Chelsea first team, he struggled for playing time as he was behind John Terry, Ricardo Carvalho and William Gallasin the centre back positions.

Robert Huthleft Chelsea to sign for Middlesbrough in August 2006. Boro paid around £6m to sign the German central defender from Chelsea. He signed for Stoke City for a then club-record transfer fee of £5m on the back of his three-year spell at Boro.

Huthwon the Player of the Year award at Stoke City at the end of the 2010/11 season. He was rewarded for an impressive season which saw him play in the FA Cup final for the Potters. Robert Huth was one of the best Stoke City players during the run to the FA Cup final before they were beaten 1-0 by Manchester City thanks to the goal from Ivorian player Yaya Tourein the second half.

Tony Pulis was the Stoke City manager when they played in the 2011 FA Cup final and Robert Huth remained an integral part of the Potters squad under his management during the 2011/12 and 2012/13 seasons. He was also a regular under new manager Mark Hughes during the 2013/14 season before a serious knee injury ruled him out of action for almost a year. Huth was unable to force his way back into the starting XI when he returned from the serious knee problem.

Robert Huth joined Leicester City on loan from Stoke City in February 2015 and he played a key role to help the Foxes preserve their Premier League status. He joined Leicester City permanently and went on to lift the Premier League title with the club in 2016.

On the international stage, Huth scored twice in 19 games for Germany over a five-year period.
