Hamburg general manager Frank Arnesen has confirmed that the club have signed Per Ciljan Skjelbred.
The Bundesliga outfit have enjoyed a productive summer in the transfer market, with the likes of Michael Mancienne and Jeffrey Bruma brought in on permanent and loan deals respectively.
The re-building project shows no sign of slowing down, with Norway international Skjelbred the latest to be snapped up.
He will head to Germany from Rosenborg and is expected to sign a contract which will tie him to Hamburg until June 2015.
It was initially suggested that he would not make the move until January 2012, at the end of his deal with Rosenborg.
Arnesen, though, claims an agreement has been put in place that will see the 24-year-old arrive in the Bundesliga in time for the start of the 2011/12 campaign.
He told the club's official website: "We have an agreement for Per Ciljan Skjelbred to arrive at our club earlier than we first expected.
"If everything goes to plan, he will arrive at our club on 3rd or 4th August. We are happy to have him available for the first phase of the new season."
Meanwhile, as he gets ready to welcome one new arrival, Arnesen has revealed that Hamburg are looking to offload Mikael Tavares.
The former Middlesbrough loanee is deemed to be surplus to requirements at the Imtech Arena and is currently taking in a trial at French outfit Dijon.
Arnesen said: "We had talks five weeks ago. The result was that he is free to find himself a new club. So far things have not worked out for him."
