Frank Arnesen is set to visit London on Tuesday to recruit a number of Chelsea reserves to join him at Hamburg.
The sporting director worked at Stamford Bridge until last summer, when he moved to HSV and brought with him five players from the Premier League outfit. And now, he is hoping to make further additions.
"I have three or four appointments," he told Bild. "We do not have much money. For something to happen, the players must be good."
Last summer, Arnesen signed Jeffrey Bruma on a one-year loan deal, and made permanent moves for Gokhan Tore, Jacopo Sala, Michael Mancienne and Slobodan Rajkovic, who cost a combined €4 million.
And in addition to bringing in more Chelsea reserves, Arnesen hopes to exercise an option to extend Bruma's loan spell for another year.
"I do not want to wait until June 1 to have clarity," he said. "I know that there will be no decision now, but I would like to have a sense of how it looks."
Arnesen also asserted that while several days have passed since Rene Adler completed his medical and no word of a final deal has been revealed, negotiations to sign the Bayer Leverkusen goalkeeper have not broken down.
"This is the normal procedure for a player of his calibre. I have no problem if it takes three or four weeks," the Dane explained.
Adler, whose contract with Leverkusen is set to expire in the summer, has long been linked with a free transfer to Hamburg, having fallen out of favour with Robin Dutt's side during an injury spell.
Meanwhile, Hamburg have confirmed that experienced striker Mladen Petric will not be offered a new contract and will leave the club in the summer, with Arnesen stating: "We want to focus more on young players and continue to streamline our salary structure."
Finally, the club have confirmed that Maximilian Beister has signed a new contract which will extend his stay at the Imtech Arena till 2016, with the attacker currently on loan at Fortuna Dusseldorf.
"We are very happy that a young, highly talented player like Maximilian has shown long-term loyalty [to the club]," Arnesen added.
The 21-year-old Beister has scored 10 goals and provided 12 assists in 24 appearances this season in the 2. Bundesliga. He had attracted interest from Borussia Monchengladbach but is now expected to be pushing for a first-team role at HSV next season.
