Hamburg chairman Carl-Edgar Jarchow has admitted interest in AZ Alkmaar midfielder Rasmus Elm.
The 24 year old Swedish international is also a target for Premier League giants Liverpool and Manchester United.
It is said that the German club have also previously been linked with a bid for Elm, who joined AZ from Swedish side Kalmar FF in 2009.
Hamburg-based billionaire Klaus-Michael Kuehne is reportedly ready to help fund the deal.
“We are talking frequently [with Kuehne] and we are talking about many things,” said Jarchow.
“Elm is definitely a player that has been making our shortlist.”
