Heiko Westermann (born 14 August 1983) is a German former professional footballer who is currently the assistant coach of La Liga club Barcelona.

[13] Shortly after his contract with Ajax had been dissolved, Westermann signed a two-year deal with Austrian side Austria Wien.

On 2 June 2009, Westermann scored the first international goal in Germany's 7–2 rout against United Arab Emirates national football team.
