Football Association chairman Greg Clarke has condemned the "inappropriate, disrespectful and disappointing" behaviour of some England supporters during Wednesday night's friendly against Germany.

England's 1-0 defeat in Dortmund was marred by supporters who booed the German national anthem and then sang distasteful songs referencing the First and Second World Wars.

Clarke's statement came as the FA and police are expected to review video footage in a bid to identify, and potentially ban, those involved.

Clarke confirmed the FA was working with the England Supporters Travel Club and speaking with the Football Supporters' Federation in the aftermath.

The Football Supporters' Federation earlier condemned the vile chants that overshadowed a promising performance from Gareth Southgate's young team and undermined what they said was a long bid to improve England fans' standing abroad.

"Over the last 20 years English football fans have built a worldwide reputation for our passionate support and the vocal backing we give to our teams," the spokesperson said.

"Unfortunately, little of the wit and imagination that goes into our club football songs is reflected at England games."

The spokesperson said the chants had also angered many England fans who had made the trip to Dortmund.

"England's travelling support is made of people of all ages from a range of clubs, many of whom have worked hard in recent years to improve our standing abroad and have expressed concern to us about these chants.

"We don't want to regress to a situation where that reputation is tarnished by the actions of a minority."

England manager Southgate stopped short of condemning supporters during Wednesday's post-match press conference but urged the travelling fans to back their side in the "right way".
